what are 2 differences btwn cat and human in pectorals group

long, tough, anterior to calcaneus

tibialis anterior

covers anterior portion of lower hind leg; originates on tibia and insenrts by meands of tendon. extends and inverts foot

flexor digitorum longus

lies on medial aspect of lower hind leg next to tibia. arises from it and inserts on phalanges. flexes digits.

adductor longus

narrow muscle similar to adductor femoris. belongs to adductors of thigh

gluteus medius

originates primarily from the ilium, last sacral and first caudal vertebrae to insert on the greater trochanter; abducts thigh

lumbodorsal fascia

connects the latissimus dorsi to its origins on the thoracic, lumbar and sacral vertebrae, as well as the iliac crest

acromiotrapezius

arises on the middorsal line of the neck and thorax and inserts on the metacromion and spine of the scapula) adducts the scapula

caudofemoralis

smaller muscle just anterior to the biceps femoris

semitendinosus

anterior to semimembranosus

clavotrapezius

arises from the back of the skull and middorsal line of the neck and inserts on the clavicle. Its action is to extend the humerus in a forward direction.

spinodeltoid

arises from the scapula spine and inserts on the proximal portion of the humerus

spinotrapezius

arises from the spinous processes of thoracic vertebrae and inserts on the fascia covering the scapular muscles. Its action is to adduct the scapula and pull it posteriorly

clavodeltoid

It arises from the acromion process of the scapula and inserts on the spinodeltoid muscle.

gluteus maximus

muscle immediately anterior to the caudofemoralis

biceps femoris

lies posterior to the tensor fascia latae and fascia lata. It is a very broad and thick muscle which arises from the ischium and inserts from the patella to the middle of the shaft of the tibia by means of a wide aponeurosis.

acromiodeltoid

posterior to the clavodeltoid. It arises from the acromion process of the scapula and inserts on the spinodeltoid muscle.

pectoantebrachialis, xiphihumeralis, trapeziuses, deltoids, lumbodorsal fascia, adductor femoris
