Question

Long uninucleate muscles are found in
A.Diaphragm
B.Alimentary canal
C.Tongue
D.Eye

Answer 1

Hint:
Muscles are made up of elastic tissue. Thousands of muscle fibers constitute elastic tissues. These muscles work together with the nerve fibers to do all voluntary and involuntary functions of the body. uninucleate muscles are involuntary muscles.

Complete answer:
Uninucleate muscles contain a single nucleus. Smooth muscles are uninucleated and nonstriated. It is constituted of unbranched small cells that are spindle-shaped and have centrally located nuclei. They are regulated by the autonomic nervous system.
The cytoplasm of smooth muscles contains a large amount of myosin and actin. These are the main protein proteins involved in the contraction of muscles. In addition to this, it contains thick and thin filaments arranged in a non-striated pattern.
Smooth muscles are called involuntary muscles. These muscles work without our consciousness. Different types of body movements are depended upon the smooth muscles. The muscles of the stomach and digestive system pupils (shrink and expanding of the pupil), and the uterus (contraction of the uterus during childbirth) constitute smooth muscles. Apart from these smooth muscles are present in the wall of the bronchi alimentary canal and bladder.
Hence the correct answer is Alimentary canal.

Option ‘B’ is correct

Note:
In the human body, more than six hundred muscles are present. Depending on the presence of muscle fibers the muscle strength varies. Muscles are subdivided into three types skeletal muscles, smooth muscles, and cardiac muscles. Approximately about 30%- 40% of our body weight is comprised of skeletal muscles. The skeletal muscles control all the voluntary functions of the body. The muscles that constitute the heart are known as cardiac muscles. Cardiac muscles are also known as myocardium. The cardiac muscles contract and relax tirelessly from birth to death.
