Extrinsic Muscle
Have one attachment on the limb and one attachment on
the trunk or neck/head. Their actions depend on weight distribution. They
move the limb relative to the body, but if the limb is anchored by body
weight, the body is moved relative to the limb.
Intrinsic Muscle
Are attached totally to limb bones and thus they move only joints of the limb
Subcutaneous tissue
The soft tissue immediately underlying the skin or epidermis.
Areolar tissue
Loose connective tissue that contains fat
Superficial fascia
Deep to the areolar tissue, connective tissue enveloping, separating, or binding together muscles, organs, and other soft structures of the body.
Deep fascia
Firmly attached to the muscle that it encloses
Adipose tissue
Used for cushioning, thermal insulation,
energy storage (fat)
Dense connective tissue
Forms strong, rope-like structures
such as tendons and ligaments. Tendons attach skeletal muscles to bones; ligaments connect bones to bones at joints.
