What innervates the cutaneous trunki muscle?
Lateral thoracic nerves
What innervates the superficial and deep pectoral muscles?
Superficial - cranial pectoral (C7 and C8)
Deep - caudal pectoral (C8 and T1)
What are the actions of the superficial and deep pectoral muscles?
Superficial - adduct limb
Deep - adduct, draw limb caudally, flex shoulder
What 2 nerves innervate the braciocephalicus? What are the 3 actions?
Accessory nerve and ventral cervical spinal nerves
Flex head and neck laterally, extend the shoulder, protract the limb
What innervates the trapezius? What is this muscles action?
Accessory nerve
Abduct the limb
What innervates the omtransversarius? What is its action?
Accessory nerve
Flex neck laterally
Protract the limb
What innervates the rhomboideus? What is its action?
Ventral branches of cervical and thoracic spinal nerves
Abduct limb
What innervates the latissimus dorsi? What is its action?
Thoracodorsal nerve (C7, C8, T1) Retract forelimb and flex shoulder joint
What are the 2 parts to the serrates ventrally? Which one protracts and retracts?
Serrates ventralis cervicis (cranial - retracts)
Serrates ventralis thoracis (caudal - protracts)
What is the innervation and action of the serrates ventralis?
Ventral branches of cervical spinal nerves, long branches of thoracic spinal nerves
Supports the trunk, depressors the scapula, protracts and retracts forelimb
How many superficial cervical lymph nodes are they? What parts of the body do they drain?
2
Caudal and lateral neck, forelimb
Which muscle acts as the lateral collateral ligament of the shoulder joint?
Infraspinatus
How many heads of triceps are there in dog and horse?
Dog - 4 (medial, long, lateral, accessory)
Horse - 3 no accessory
Where is the biceps tendon found? What holds this in place?
Intertubercular groove Transverse ligament (humerus)
What distal FL muscle is an extensor in the dog, but flexor in the horse?
Ulnaris lateralis
