extrinsic mm.

3

Intrinsic mm.

4

Muscles that stabilize the shoulder e.g. supraspinatus, infraspinatus

Shoulder mm

5

Grouped into flexors and extensors of the elbow

arm muscles: Brachium

6

Innervated by the radial n. they cross the extensor side of the elbow to insert on the olecranon

Extensors of the elbow

7

Cross the flexor side of the elbow

flexors of the elbow

8

divided into flexors and extensors of the carpus and digits

Forearm (ante brachial) muscles

9

located craniolaterally, they are innervated by the radial nerve

Extensors of the digits and carpus

10

Muscles located caudally

Flexors of the carpus and digits

11

insignificant m, except the interosseous m (suspensory ligament in horses)

Muscles of the manus and pes

12

Functioning in respiration, they are divided into inspiratory and expiratory muscles

Thoracic muscles

13

Arise cranial to the thorax and move the ribs cranially and laterally thus increasing the volume of the thorax , resulting in the air rushing into the thorax sue to decreased pressure

inspiratory mm

14

the major inspiratory muscle it retracts caudally to increase the size of the thorax, thus resulting in inspiration

Diaphragm

15

arise caudal to the thorax and move the ribs caudally and medially, decreasing the volume and increasing the pressure, forcing air out

expiratory muscles

16

three lateral muscles and the rectus abdominis on the ventral abdomen

abdominal wall muscle

17

flat tendons of the lateral abdominal muscles that form a sheath around the rectus abdomens

aponeuroses

18

the straight abdominal muscle on either side of the midline, running longitudinally

rectus adbominis

19

aponeuroses of the abdominal mm covering the rectus abdominis

external rectus sheath

20

the muscles located above the transverse processes of the vertebrae

Epaxial mm

21

muscles located below the transverse process of the vertebrae

hypaxal mm

22

hypaxial m. located ventral to the bodies of the cervical vertebrae

Longus Coli m.

23

arise from the sternum and the extend cranially on the ventral midline of the neck, just superficial to the trachea

strap mm

24

pass from ventral surface of the thoracic and lumbar vertebrae to the hip bone and femur

Sublumbar mm

25

Muscle that extend the hip

Rump or gluteal muscles

26

27

the adductor group inneravted by the obturator n. They adduct the limb

Adductor/ medial thigh mm

28

Innervated by the sciatic n they extend the hip joint and have varied actions on the stifle and tarsus

caudal mm of the thigh/ hamstring mm

29

Craniolateral mm innervated by the common fibular nerve

33

innervated by the mandibular division of the trigeminal nerve

34

connect the eye and the body, move the eye and are innervated by the 3rd and 4th, and 6th cranial nerve

35

innervated by the hypoglossal n.

muscles of the tongue

36

deal with swallowing and are innervated cranial nerve 9 and 10

muscles of pharynx

37

joining of many ventral branches of the cervical nerves, supplying structures to the neck

cervical plexus

38

a network formed by ventral branches of the last few cervical nerves, and the first on or two thoracic nerves. supplies most muscles of thoracic limb
