hair and females's mammary glands to nourish young
what are the two main characteristics that distinguish mammals form other animals
this is something an animal has that reveals its diet; looks at the types of teeth, number, arrangement, etc.
cat's dentition pattern
what does the sharp and point incisors and canines from front and premolars in rear indicate in a cat?
how it walks
cat's gait; walks on digits with remainder of foot elevate
human walk; on entire side of foot
on the nose
on ears, long, flexible extrernal fold that directs sound waves into extrnal auditory meatus
on eyes, greatly reduced, also called plica semilunaris
long sensory hairs on face, also called pini tactiles.

lies deep to sternohyoid and lateral to it
v shaped, extends from occipital bones to mandible and lowers jaw
fibers of this mucle run transversely btwn digatric in mid ventral are. pass deep to digrastric and raises floor of mouth
most anterio muscle in shoulder, originates at clavicle, and inserts on ulna. continuation of clavtrapezius. works with it to extend humerus, turn head, and flex elbow
thin superficial muscle on medial surface of humerus. originates from ventral border of latissimus dorsi. inserts by thin aponeurosis on lower forelimb. acts with triceps brachii as extensor of elbow. not in human
three heads, long head is partially visible, extends forearm
anterior to lateral head of triceps. arises fof humerus and inserts on ulna, flexes elbow
covers muscles of lower forelimb, tough layer of fascia
most anteiror of these muscles, origina on humerus and insertion radis. rotatses it and supinates paw
etensor carpi radialis longus
inserts on second metacarpal and extends forefoot.
extensor digitorum communis
long muscle whose tendon divides at wrist and attaches to digits, which it extends
extensor digitorum laterialis
long muscle of lower forelimb, inserts on digits and extends them
extensor carpi ulnaris
inserts on fifth metacarpal
flexor carpi ulnaris
origin is at hdistal humerus and inserts at carpals-flexes writs and adducts hand
adjacent to flexor carpi ulnaris, moves medially, flat muscle oriiginates on jumerus and inserts on phalanges.
long, narrow band-like muscle that passes along medial border of forearm.
flexor carpi radialis
origin on humerus and inserts on metacarpals, extends manuys of wrist
origin on bottom of humerus and inserts on raidal shaft, pronates manus at wrist
external jugular vein
receives blood from skin and muscles of head
anterior facial vein
colelcts blood from face, tongue, etc
posterior facial vein
arisis from region of internal maxillary. collects blood from masseter and temporal muscles
transverse jugular vein
short but prominent vein that crosses the midline and unites with external jugular vein.
small portion at insertion of femur, muscle arising from lumbar vertebral and illum
narror muscle similar to adductor longus; posterior to femoral artery and vein
anterior to gracilis; originates from pubis and inserts femur
located beneath gracilis, posterior to adductor longus and femoris
occipies anterior half of thigh; flat and broad that inserts on tibia and fibula; adducts and rortates thigh adn extends it
major muscle of calf; has two heads and inserts on calcaneues. extends foot
deep to gastrocnemius; originates on fibula and inserts on calcaneus; extends foot
long, tough, anterior to calcaneus
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.
narrow muscle similar to adductor femoris. belongs to adductors of thigh
originates primarily from the ilium, last sacral and first caudal vertebrae to insert on the greater trochanter; abducts thigh
connects the latissimus dorsi to its origins on the thoracic, lumbar and sacral vertebrae, as well as the iliac crest
arises on the middorsal line of the neck and thorax and inserts on the metacromion and spine of the scapula) adducts the scapula
smaller muscle just anterior to the biceps femoris
anterior to semimembranosus
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.
arises from the scapula spine and inserts on the proximal portion of the humerus
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
It arises from the acromion process of the scapula and inserts on the spinodeltoid muscle.
muscle immediately anterior to the caudofemoralis
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.
