1

Trapezius attachments

funicular portion of nuchal ligament to scapular spine

2

Rhomboideus

nuchal ligament and dososcapular ligament C2-T8 to scapular cartilage

3

Omotransversarius attachments

shoulder fascia to transverse processes of cervical vertebrea (c2-c4); if something is attaching to multiple CV its omotransversarius

4

Splenius attachments

funicular portion nuchal ligament from withers to poll, transverse processes of cervical vertebrea

5

subclavius attachments

often considered component of deep pectoral muscle; manubrium and sternum to supraspinatus and shoulder fascia; lies cr to cr aspect of scapula

6

Omohyoideus attachments

shoulder fascia to basihyoid

7

Sternocephalicus attachments

manubrium to cd border of mandible

8

Sternothyroideus attachments

manubrium to thyroid cartilgage

9

Sternohyoideus attachments

manubrium to basihyoid

10

Serratus ventralis attachments

transverse processes of cervical vertebrea c4-c7, first 8-9 ribs, dorso-medial scapula

11

Latissimus dorsi attachments

thoracolumbar fascia to teres major tuberosity (medial humerus); extrinsic limb muscle

12

Cutaneous trunci

innervated by lateral thoracic nerve; makes skin twitch in response insects/ stimuli ect

13

brachiocephalicus fx

extends the limbs if the limb fixed will pull head to the side

14

scaleneus attachments

1st rib to transverse process of CV

15

serratus ventralis fx

suspends trunk, raises neck when forelimb is fixed, supports inspiration

16

omohyoideus fx

synergistic with hyoid muscles to retract laryxn

17

rhomboideus fx

elevates neck and draws scapula dorsocranially; draws dorsal end of scapula toward midline

18

scalenus fx

flexes neck or bends it laterally

19

Longissimus attachments

transverse processes to skull, wing of atlas, other transverse processes

20

longisimus fx

flexes neck or bends it laterally

21

semispinalis capitus attachments

CV and transverse processes of first 8 thoracic vertebrea of skull (part of transversospinalis muscle group)

22

epaxial medial to lateral

transversospinalis, longisimus, iliocostalis

23

semispinalis is a named type of which epaxial muscle

transverso spinalis

24

iliocostalis

long white tendons attach to ribs, sacrum -> cd cervical neck

25

longus muscles

longus Colli and longus capitus

26

Longus colli attachments

transverse process of CV and bodies of thoracic vertebrea to body of CV, other transverse processes, and ventral atlas

27

Longus colli fx

flex neck laterally

28

Longus capitus attachments

transverse processes of C3-C5 to base of skull

29

Longus captius fx

flex neck laterally, elevate the head and neck as it bends laterally

30

sternohyoideus fx

retract hyoid
