The distal phalanx in equine is flat
27
Label the following:
28
29
What are some differences found in the palmar side of an equine thoracic digit compared to a canine
* The medial proximal sesamoid is bigger & more triangular shaped * There is a proximal phalangeal trigone (an attachment site for multiple ligaments) * There is a medial & lateral solar foramen with a canal connecting the two
30
Label the following:
31
what does spheroid mean when discussing joints
That the joint can do all ranges of movement
32
Describe the humeral joint in equine
* Is a Simple spheroid joint but acts like a hinge joint * Is involved in flexion and extension movements * Has glenohumeral ligaments that act as a thick capsule on the medial & lateral side * Has a thick biceps brachii origin tendon & a bursa
33
What is circled in pink?
The biceps brachii origin tendon
34
There is a ____ capsule surrounding the entire carpal area
Full
35
What type of joint is the antebrachiocarpia (radiocarpal) joint
Hinge
36
What type of of joint is the intercarpeae (intercarpal) joint
Plane
37

Hinge
38
What type of joint is the carpometacarpeae (carpometacarpal) joint
Plane
39
Describe the carpal joints in equine
* They are similar to other species * The radiocarpal joint is surrounding the radius & proximal carpal row * The sinovial capsule of the radiocarpal joint is independent * The sinovial capsule of the inter & Mediocarpea is a shared capsule * Consist of the lateral colateral & medial colateral ligaments
40
What does anti degree does the radiocarpal allow
90 degrees
40
What carpal joint has the most range of movement & how many degrees of motion (midcarpal joint)

What is the red line
Radiocarpal joint
41
Describe the capsule joint between the proximal carpal bones & the metacarpal joint (carpometacarpal joint)
* The bones just slide * There is not much range of motion
42
What is the blue for
* The top = Mediocarpea (midcarpal) joint * The bottom = Carpometacarpeae (carpometacarpal) joint
43
What is circled in pink
