Popliteal fossa

the hollow at the back of the knee

Sciatic nerve

nerve running deep to the gluteus maximus; typically deep to the piriformis but sometimes superficial to it or piercing through it

Thoracolumbar fascia

Biceps brachii origin

short head: coracoid process of scapula

long head: supraglenoid tubercle of scapula

Biceps brachii insertion

radial tuberosity and bicipital aponeurosis

Biceps brachii action

flexes shoulder and elbow; supinates forearm

Biceps brachii innervation

musculocutaneous nerve

Deltoid origin

lateral 1/3 of the clavicle; acromion; spine of the scapula

Deltoid insertion

deltoid tuberosity of the humerus

Deltoid actions

anterior fibers: flex and medially rotate shoulder

posterior fibers: extend and laterally rotate shoulder

all fibers: abducts the shoulder

Deltoid innervation

axillary nerve

Diaphragm origin

xiphoid process; costal margin; vertebral bodies L1-L3

Diaphragm insertion

central tendon

Diaphragm action

presses the abdominal viscera inferiorly, increasing the volume of the thoracic cavity

Diaphragm innervation

phrenic nerve (C3-C5)

Gastrocnemius origin

lateral head: lateral condyle of the femur

medial head: medial condyle of the femur

Gastrocnemius insertion

calcaneus

Gastrocnemius action

knee flexion and plantar flexion of the ankle

Gastrocnemius innervation

tibial nerve

Occipitofrontalis origin

occipitalis: superior nuchal line

frontalis: epicranial aponeurosis

Occipitofrontalis insertion

occipitalis: epicranial aponeurosis

frontalis: SQ tissue of eyebrows

Occipitofrontalis action

wrinkles forehead and elevates eyebrows

Occipitofrontalis inervation

facial nerve (CN VII)
