NEET Important Questions Locomotion and Movement

National Eligibility cum Entrance Test (undergraduate), together with stands for NEET (UG). It is a medical entrance exam mainly for the students who want to pursue the same as their careers. It was formerly known by the name of All India Pre-Medical Test (AIPMT) and later was altered to NEET (UG), which happens to take place once a year. The courses which are wide open after applying for NEET include BDS, MBBS, BAMS, BUMS, BHMS, etc. It is a total three-hour exam which is conducted by the National Testing Agency (NTA). It was the year 2019 when NTA came into power for the conducting of NEET. Earlier it was in the hands of the Central Board of Secondary Education from the year 2013 to 2018. NTA is the governing body for not only NEET but also is responsible for the smooth conduct of JEE MAINS, CMAT, GMAT, and NET. The National Eligibility cum Entrance Test is an important exam for entering the line of a career which one is willing to. It should not at all be considered as a child's play and hence asks for a good amount of concentration and rigorous study when applying for the same. For students to score respectively well, they should create the right timetable and follow it with as much sincerity as they motion3-hour can get. Talking about NCERT, it is not counted as a sufficient publisher from which one should be studying. Students should opt for different publishing books and study materials which will only help them to do better than good in exams such as NEET. Basics need to be covered but deeper knowledge is also important to score well, and hence it is advisable to move out of the box with different sample papers and question banks.


Certain questions are asked repeatedly throughout the NEET exams which are conducted every year. Students should pay good attention to them as their chances to be present even at the current NEET is relatively higher only. Every important question and topic of the chapter locomotion and movement is important concerning the syllabus of NEET. Vedantu, on the other hand, can play a vital role in the preparation of NEET. It carries a wide variety of questionnaires and sample papers which are essentially beneficial for any primary, secondary student or even who are applying for any competitive exams. Students should go through these Important Questions because to score good students must know about the topics that are repetitive as well as important and these topics will help them in scoring good marks.

Topics of Locomotion and Movement

1. Types of Movements (Ciliary, Flagellar, Muscular):

  • Ciliary Movements: Envision microscopic hair-like structures, called cilia, lining surfaces. Their coordinated waving motion helps move substances along surfaces, like in the respiratory tract, aiding in the expulsion of mucus and particles.

  • Flagellar Movements: Think of flagella as whip-like tails, commonly found in sperm cells. Flagellar movements propel the sperm forward, facilitating its journey towards the egg during fertilization.

  • Muscular Movements: Explore the versatility of muscle movements in the body, from the rhythmic beating of the heart (involuntary) to intentional actions like walking and lifting (voluntary).


2. Skeletal Muscle - Contractile Proteins and Muscle Contractions:

  • Skeletal Muscle: These muscles are connected to bones and allow for voluntary movements. They work in pairs, contracting and relaxing to produce motion. 

  • Contractile Proteins: Within skeletal muscles, actin and myosin are contractile proteins. Their interaction causes muscle contraction by shortening the muscle fibers.

  • Muscle Contractions: Understand the mechanism of muscle contractions – the sliding of actin and myosin filaments – which is fundamental to all voluntary movements.


3. Skeletal System and Its Functions:

  • Skeletal System: Visualize the skeleton as a supportive framework composed of bones. It provides structure, shape, and support to the body.

  • Functions: Beyond support, bones protect vital organs, anchor muscles for movement, and serve as a reservoir for minerals like calcium and phosphorus.


4. Joints:

  • Description: Joints are where two or more bones meet, allowing various degrees of movement. Examples include hinge joints (elbows, knees) and ball-and-socket joints (shoulders, hips).

  • Role: Joints facilitate a wide range of motions, from simple hinge-like movements to rotational actions, crucial for daily activities.


5. Disorders of Muscular and Skeletal System (Myasthenia Gravis, Tetany, Muscular Dystrophy, Arthritis, Osteoporosis, Gout):

  • Myasthenia Gravis: Explore an autoimmune disorder where the immune system attacks receptors on muscle cells, leading to muscle weakness.

  • Tetany: Understand a condition caused by low blood calcium levels, resulting in muscle spasms and cramps.

  • Muscular Dystrophy: Delve into a group of genetic disorders causing progressive muscle degeneration and weakness.

  • Arthritis: Recognize the inflammation of joints, leading to pain and decreased mobility.

  • Osteoporosis: The condition characterized by weakened bones, making them more susceptible to fractures.

  • Gout: Understand a type of arthritis caused by the accumulation of uric acid crystals in joints, resulting in severe pain and inflammation.


Important Question for Locomotion and Movement 

1. What is the primary function of ciliary movements in the human body?

Answer: Ciliary movements help in moving substances along surfaces, facilitating processes like the clearance of mucus and particles in the respiratory tract.


2. How do contractile proteins, like actin and myosin, contribute to muscle contractions?

Answer: Actin and myosin interact within skeletal muscles, causing the filaments to slide and leading to muscle contractions by shortening the muscle fibers.


3. Provide an example of a ball-and-socket joint in the human body and explain its role in movement.

Answer: The shoulder joint is a ball-and-socket joint. It allows for a wide range of rotational movements, crucial for activities like lifting and reaching.


4. What is the main function of the skeletal system, and how does it contribute to locomotion?

Answer: The skeletal system provides structural support to the body and protects organs. It anchors muscles, enabling movements like walking and running.


5. Explain the process of muscle contraction in detail, highlighting the role of contractile proteins.

Answer: Muscle contraction involves the interaction between actin and myosin filaments within skeletal muscles. The sliding of these filaments shortens muscle fibers, resulting in the contraction. The process includes various stages, such as muscle fiber excitation and the release of calcium ions.


6. Discuss the significance of joints in the human body, providing examples of different types and their functions.

Answer: Joints play a crucial role in facilitating movement. Hinge joints, like the elbow, allow bending and straightening, while ball-and-socket joints, like the hip, permit a wide range of motions, including rotation. Understanding joint types enhances our comprehension of the diversity of movements in the body.


7. Explore the impact of disorders such as arthritis, osteoporosis, and muscular dystrophy on the musculoskeletal system, detailing their symptoms and potential consequences.

Answer: Arthritis causes joint inflammation, leading to pain and reduced mobility. Osteoporosis weakens bones, increasing the risk of fractures. Muscular dystrophy results in progressive muscle degeneration and weakness. Understanding these disorders is crucial for recognizing symptoms, seeking appropriate medical attention, and managing their effects on the musculoskeletal system.

FAQs on NEET Locomotion and Movement Important Questions

1. Define different types of movements.

Movements that help in changing the place are known as locomotion. The moments are vividly divided into three kinds:


1. Ciliary and Flagellar movement

This kind of movement happens in the epithelial lining of the reproductive lining, trachea, etc. Sperms also show moment that ais flagellar


2. Amoeboid Movement 

This movement is like that movement that is known as pseudopodia in amoeba. Leukocytes, macrophages and cytoskeletal microfilaments also determined Amoeboid movement.


3. Muscular Movement 

These kinds of movements are responsible for the movements in multicellular organisms. Functions like breathing, heart-related functions, locomotion and other movements are also performed by various muscles in the body of multicellular beings like humans. Locomotion is nothing but the coordinated movement of the neural, muscular and skeletal systems.

2. What are the types of muscles?

Three different types of muscles are responsible for different moments:


1. Visceral Muscles

These kinds of muscles are smooth and non-stretched. They are involuntary muscles and also support various internal organs. These muscles take part in many functions like reproduction, digestion, etc. 


2. Cardiac Muscles

These kinds of muscles are involuntary and are also striated. These muscles are only present in our hearts. 


3. Skeletal Muscles
These muscles are voluntary and are striated like cardiac muscles. These muscles are responsible for the movement of appendages and locomotion as well.

3. What are Muscle Fibers? Explain

Elongated Cells are present in our bodies known as muscle fibres. These muscle fibres are organized into bundles known as fascicles. The feature of muscle fibres are listed below:

  1. Muscle fibres are syncytium, which means that they have many nuclei

  2. Musch fibres are long, cylindrical and as well as striated 

  3. The sarcolemma is the membrane of plasma in the muscle fibres 

  4. Sarcoplasmic in the cytoplasm 

  5. The sarcoplasmic reticulum is endoplasmic. These reticular are storehouse of Ca ions

4. What is Muscle Relaxation?

When the signals of neural stop or ceases, Acetylcholinesterase processes the acetylcholine in the cleft known as the synaptic cleft. After this, the muscle fibres come to a rest and finally to the resting state. While muscle rests, the Ca ions are being pumped back into the sarcoplasmic reticulum. When the Ca ions are absent, the troponin-tropomyosin complex starts to cover the myosin-binding via filaments that are actin. The Z line of the sarcomere then returns to the original position and then finally the muscles are relaxed.

5. Explain any two of the muscle diseases

There are many diseases, here we will talk about two such diseases:


1. Tetany 

This disease is caused due to calcium deficiency. This can be identified by the involuntary muscle contractions 


2. Tetanus

This is a bacterial disease. The cause of this disease is an organism known as clostridium tetani. The toxic that is given out of this bacteria presents is the same as that of acetylcholine and this binds to the receptors irreversibly. This causes very severe painful contractions.
