====Muscles of the Carpal and Digital Joints====
==Extensors==
''Interosseus muscles''
All have innervation from the radial n. from the brachial plexus. They have a craniolateral position on the forearm and almost all of them originate from the lateral epicondyle of the humerus.
'''Extensor carpi radialis''': The most medial, inserts on 2nd/3rd metacarpal bone.
'''Ulnaris lateralis''': The most lateral, inserts on accessory carpal bone.
'''Extensor carpi obliquus''': aka '''abductor pollicis longus'''
Origin: cranial radius.
Insertion: most medial metacarpal bone .
'''Common Digital Extensor'''
Insertion: extensor process of the distal phalanx of each digit.
'''Lateral Digital Extensor'''
Insertion: dorsal proximal phalanges.
'''Medial Digital Extensor'''
Insertion: middle and distal phalanges.
==Flexors==
All innervated by the median or ulnar n. of the brachial plexus. Have a caudal position on the forearm and originate from the caudal medial epicondyle of the humerus.
'''Flexor carpi radialis'''
The most medial, inserts on upper 2nd/3rd metacarpal bone.
'''Flexor carpi ulnaris'''
The most lateral, inserts on the accessory carpal bone.
'''Superficial Digital Flexor'''
Insertion: palmar surface of middle phalanges.
'''Deep Digital Flexor'''
Passes through carpal canal before branching and continues to palmar distal phalanges.
'''Interosseus muscles'''
This is covered in more detail in the [[Bovine Phalanges - Anatomy & Physiology|bovine phalanges]] section.
