Deep digital flexor muscle
Musculus flexor digitorum profundus
Flexes the digits, particularly the distal interphalangeal joints, and aids carpal flexion.
About the deep digital flexor muscle of the dog
Deep digital flexor muscle is a muscle of the front leg (thoracic limb), one on each side of the body. Its name in the Nomina Anatomica Veterinaria is Musculus flexor digitorum profundus. Deepest caudal forearm muscle, against the bones. You can turn it above, see it in place in the front leg of the dog, and open it inside the whole animal in Vetomica.
Where it runs from and to
A muscle is told apart from its neighbours by what it takes hold of at each end, which is also what decides what it does when it shortens.
- Origin
- Humeral head from the medial epicondyle; ulnar and radial heads from the caudal ulna and medial radius.
- Insertion
- Deep flexor tendon branches reach the palmar tubercles on the distal phalanx of every digit.
- Action
- Flexes the digits, particularly the distal interphalangeal joints, and aids carpal flexion.
- Nerve
- Median and ulnar nerves.
