Tendons/Ligaments/Nerves Flashcards
What provides motor innervation to the flexors of the elbow?
Musculocutaneous nerve
What are the flexors of the elbow?
Biceps brachii, coracobrachialis, brachialis
What does the axillary nerve innervate?
Flexors of the shoulder
What are the flexors of the shoulder?
Teres major, teres minor, deltoid
The axillary nerve provides sensory information to what part of the thoracic limb?
Cranial arm and forearm
What does the radial nerve innervate?
Extensors of the elbow, carpus, and digits.
What are the 9 extensor muscles of the distal thoracic limb?
- Triceps brachii
- Anconeus
- Tensor fasciae antebrachii
- Extensor carpi radialis
- Common digital extensor
- Lateral digital extensor
- Lateral ulnar
- Oblique carpal extensor
- Supinator
What nerve provides sensory information to the proximal suspensory area?
Deep branch of lateral palmar nerve
The deep branch of the lateral palmar nerve gives off what structures?
Medial and lateral metacarpal nerves
What do the medial and lateral metacarpal nerves innervate?
Sensory information to the fetlock
What branch innervates the toe?
Dorsal branches of medial and lateral digital n
What does the median nerve innervate?
Most of the flexors of the forearm
What are the order of the nerves from proximal to distal in the thoracic limb?
Median & ulnar nerve –> medial & lateral palmar nn, respectively
Lateral palmar nerve gives off deep branch at level of carpus
Deep branch of lateral palmar nerve –> medial and lateral metacarpal nerves
Communicating branch between medial and lateral palmar nerves at level of mid-metacarpus
Medial and lateral palmar nerves –> medial & lateral digital nerves (distal to fetlock)
Dorsal branches of digital nerves at level of fetlock
Since 90% of equine lameness is in the foot, what 3 blocks are most important?
1) Palmar digital
2) Abaxial sesamoid
3) Low palmar/Low 4 point block
What does the palmar digital nerve block anesthetize?
Heel area of foot & all structures of the hoof EXCEPT dorsal coronary band
- Blocks medial & lateral digital nerves
