Concept explainers
To explain:
The muscle compartments and the connective tissue that separate them.
Introduction:
Muscle is a bundle or band of fibrous tissue present in a human or animal body. It can contract and move in preserving the position of body parts. Muscles play a role in the production of force and motion. They are mainly responsible for sustaining and shifting posture, locomotion.
Explanation of Solution
Muscles are linked to bones by the help of tendons. These muscles help in the movement of bones. The ligament can be defined as a short band of flexible, tough, and fibrous connective tissue. A thin and threadlike structure which combines to form plant or animal tissue is known as a fiber.
The fibrous sheets of connective tissues are known as fasciae in the limbs. These fasciae enclose the spaces known as compartments. Every compartment has one or more functionally associated muscles along with their nerve and blood supplies.
For example,the compartmentalization in the pelvic floor and abdominal wall. Also, the muscles of the upper limb are divided into anterior and posterior compartments. While the lower limb is divided into the anterior, posterior, medial and lateral compartments.
Intermuscular septa are the thick fasciae that separate the major compartments.
The fibrous sheets of connective tissues are known as fasciae in the limbs. These fasciae enclose the spaces known as compartments.
