SUPERFICIAL FASCIA OR SUBCUTANEOUS TISSUE

It is a membranous lamina consisting of fibro-areolar tissue, the meshes of which are filled with fatty or adipose tissue. Therefore, it is also known as Panniculus adiposus. A) DEEP FASCIA It is a dense elastic membrane forming coverings for the muscles and in some cases affording for them blind surfaces for attachments. It is […]

STRUCTURES RELATED TO THE MUSCLES

TENDON They are tough whitish cords/straps varying in length and thickness, and are almost inextensible. They comprise numerous parallel Fascicles (bundles) of collagen fibres and tendon cells surrounded by firbo-areolar tissue which helps to bind them together. This fibro-areolar tissue is called interfascicular tissue or endo-tenon. At the surface of the tendon the fibro-areolar tissue […]

CLASSIFICATION OF SKELETAL MUSCLE

Skeletal muscles are classified into various groups according to following scheme : I.According to the relative colour of skeletal muscle cells: In lower vertebrates for example fish and chicken the skeletal muscle cells are red (leg of chicken) or pale (breast of chicken). The distribution between the red and white muscle cells is clearly visible […]
