Bones
Landmark of the most distal region of the ulna
Styloid process
An extensor muscle that is known as the "traitor", it's origins and insertions, and it's action
Ulnaris lateralis - lateral epicondyle - proximal metacarpal five and carpal accessory bone - flexes the carpal joint
Nerves that run along the medial antebrachium
Musculocutaneous nerve, radial nerve, median nerve, ulnar nerve
Parent artery of the antebrachial region
Brachial artery
Median Artery
Relationship between the radius and the ulna in a horse
The ulna fuses with the radius and only extends half-way down the antebrachium
The articulate surface of the radius that comprise the humeroradioulnar joint
Capitus fovea
Extensor muscles, their origins, and their insertions
Extensor Carpi Radialis - lateral supracondylar crest - base of dorsal metacarpals II-III
Common Digital Extensor - lateral epicondyle - extensor process of digits II-V
Lateral Digital Extensor - lateral epicondyle - extensor process of digits III-V
Innervates the extensors of the elbow joint and the extensors of the carpal and digital joints
Radial nerve
The most distal Brachial artery branch, and it's branches
Common interosseous artery - caudal interosseous artery, cranial interosseous artery, ulnar artery
Relationship between the radius and the ulna in the bovine
The radius and ulna are fused together and both bones extend to the antebrachiocarpal joint
Ulnar tuberosity
Flexor muscles, their origins, and their insertions
Ulnaris lateralis - lateral epicondyle - proximal metacarpal V and carpal accessory bone
Flexor carpi ulnaris - medial epicondyle - carpal accessory bone
Superficial digital flexor - medial epicondyle - base of middle phalanges of digits II-V
Deep digital flexor - medial epicondyle - flexor tubercle of digits I-V
flexor carpi radialis - medial epicondyle - base of palmar metacarpal II-III
Location of median nerve and ulnar nerve
Median nerve is cranial to the medial epicondyle
Ulnar nerve is caudal to the medial epicondyle
Most proximal Median artery branch
Deep antebrachial artery
Stay apparatus of the horse that transfers tension fro the bicpes brachii muscle to the extensor carpi radialis muscle
Lacertus fibrosus
Anatomical and Layman's terms of the joints that comprise the antebrachial region, and any associated ligaments
Humeroradioulnar joint, elbow joint
Medial and lateral collateral ligaments, Interosseus ligament
Antebrachiocarpal joint, carpal joint, wrist joint
Perfect antagonists of the antebrachium, their origins and insertions, and their actions
Supinator - lateral epicondyle - proximal cranial border of the radius - flexes the elbow joint, rotate the forearm laterally
Pronator teres - medial epicondyle - proximal medial border of the radius - flexes the elbow joint, rotates the forearm medially
Pronator quadratus - border between the radius and ulna - pronates the paw
Anastimosis example nerves
Median nerve and musculocutaneous nerve anastimos at the distal antebrachial region
Carpal canal and it's association with arteries
The median artery passes through the carpal canal to supply the palmar surface of the paw
Anatomical and Layman's names for the most distal joint of the antebrachium of the horse
Radiocarpal joint, antebrachiocarpal joint, knee joint
