The distal half of the limb proper has two long bones, together termed the zeugopodium (plural: zeugopodia). These may be radius and ulna of the forearm, or the tibia and fibula of the shin. The distalmost portion or extremity of the limb, i.e. the hand or foot, is known as the autopodium (plural: autopodia).
Although the direction indicated by "proximal" and "distal" is always respectively towards or away from the point of attachment, a given structure can be either proximal or distal in relation to another point of reference. Thus the elbow is distal to a wound on the upper arm, but proximal to a wound on the lower arm. [30]
Lower limb, Gluteal, Left/right iliac crest: iliotibial tract: primarily lateral circumflex femoral artery, superior gluteal artery: superior gluteal nerve (L4, L5) flexes thigh, medially rotates thigh, stabilises torso: 2 1 gluteus maximus: Lower limb, gluteal, Left/right gluteal surface of ilium, lumbar fascia, sacrum, sacrotuberous ligament
the umbilical region is located around the navel; the coxal region encompassing the lateral (side) of hips; the pubic region encompassing the area above the genitals. The pelvis and legs contain, from superior to inferior, the inguinal or groin region between the thigh and the abdomen, the pubic region surrounding the genitals,
[12] The muscles of the upper limb are innervated segmentally proximal to distal so that the proximal muscles are innervated by higher segments (C5–C6) and the distal muscles are innervated by lower segments (C8–T1). [13] Motor innervation of upper limb by the five terminal nerves of the brachial plexus: [13]
In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. [1] Anatomists restrict the term leg to this use, rather than to the entire lower limb. [6] The thigh is between the hip and knee and makes up the rest of the lower limb. [1] The term lower limb or lower extremity is commonly used to describe ...
The distal part of the upper limb between the elbow and the radiocarpal joint (wrist joint) is known as the forearm or "lower" arm, and the extremity beyond the wrist is the hand. By anatomical definitions, the bones , ligaments and skeletal muscles of the shoulder girdle , as well as the axilla between them, are considered parts of the upper ...
The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb.It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.
