Question

Intercostal muscles are present in
A. Abdomen
B. Thigh
C. Ribs
D. Diaphragm

Answer 1

Hint:
Intercostal muscles are the group of skeletal muscles that are associated with contraction and relaxation in order to increase the cavity. In the human body, there are eleven pairs of intercostal muscles that are arranged in superficial spaces.

Complete answer:
There are majorly four types of abdominal walls that includes:- rectus abdominis, transverse abdominis, and external and internal oblique muscles and all are shaded in red. The muscle cells that are present in the stomach are unbranched, uninucleated and involuntary.
Three muscular compartments make up the thigh muscle. The anterior compartment consists of sartorius and quadriceps muscles and is pink in colour. The medial compartment consists of the pectineus, obturator externus, gracilis and adductor muscle and is green in colour. The posterior compartment consists of the bicep femoris, semimembranosus and semitendinous and is blue in colour.
There are two types of muscles present in the ribs:- internal and external intercostal muscles. These intercostal muscles help in breathing by increasing and shrinking the chest cavity.
Diaphragm itself is a muscle which is a major muscle that helps in respiration. It is a dome-shaped muscle that contracts rhythmically and involuntarily. When the diaphragm contracts upon inhalation the volume of the chest cavity increases and pulls the air into the lungs.
Thus, the correct answer is Ribs

Option ‘C’ is correct

Note:
The intercostal muscle has different layers that are attached to the ribs and help in increasing the chest volume. These muscles can tear due to any injury, or strain, or if stretched too far and can cause intercostal muscle strain.
