**Additionally the caudal angle of the scapula is more pronounced_
What are the names of the parts of the scapula shown for a cat?
-dorsal border of scapula
-caudal angle
-spine
-acromion (suprahamate process, hamate process)
what are bones labeled?
1.
what are the bones/parts labeled?
what is the midline raphe and where is it located?
layer above deep fascia and spinous process of vertebrae on the neack
what are the names of the parts labeled?
What muscles make up the extrinsic muscles?

what nerve innervates the cutaneous trunci?
lateral thoracic nerve (brachial plexus)
Which muscles make up the ventral neck? what is their innerventation?
-sternocephalicus (cervical spinal nerve and CNXI)
-sternohoyidus (cervical spinal nerve)
-sternothyroideous (cervical spinal nerve)
Extrinsic muscles attach from the ______ to the ______ skeleton or _____
-thoracic
-axial
-fascia
Extrinsic muscles connect to bones of the ______ to each other (appendicular skeleton)
leg
Is the sternocephalic an extrinsic, intrinsic muscle, or neither?
neither
Where does the nerve to the cleidobrachialis/brachiocephalicus originate?
cranial brachial plexus
What do the dorsal and the ventral nodes drain? (part of superficial cervical lymph nodes)
dorsal:dorsal neck/shoulder region
ventral: chest and front of forelimb
What is a synsarcosis? and what muscles have these?
Definition: A synsarcosis is a muscular connection between two bones. It is not a conventional joint, but serves a similar function as a conventional joint.
-ALL EXTRINSIC muscles connect to body wall via SYNARCOSES
-brachiocephalicus
-omotransversarious
-trapezius
-latissimus dorsi
-rhomboideus
-serratus ventralis
what do the serrates ventralis attachments look like?
-the serratus ventralis attaches to the transverse processes of the last five cervical vertebrae.
-he thoracic part attaches to the first seven or eight ribs. The other attachment is to the dorso-medial part of the scapula (serrated face)
Which extrinsic muscles are innervated by the brachial plexus?
SLCP
Serratus ventralis
Latissimus dorsi
Cutaneous trunci
Pectorals
What two ligaments do the cats not have?
No nuchal ligament
No organized supraspinous ligament
