Q

אילו שרירים נעלמו במפרסי הפרסה ?

איזו תנועה נמענת מהם כתוצאה מכך ובאיזה חלק?

A

השרירים:
M. brachioradialis, M.supinator ו- M. pronator quadratus אינם קיימים בבעלי פרסה ולכן הם לא יכולים לבצע תנועת
- antebrachium -סופינציה/פרונציה של ה

Q

מה ההבדל בשריר M.pronator teres

בין לכלבים ומפרסי פרסה?

A
ההבדל לעומת הכלב הוא במבנה ובתפקיד
תפקיד בסוס:
-Form the long portion of the medial collateral lig of elbow joint (thus wholly fibrous) 
–stabilization of joint.
תפקיד בכלב:
pronation of the antebrachium and manus.

Ruminants: this small muscle is also fibrous but retains some of its original nature.
It lies cranial to the M. flexor carpi radialis.

נשאר זהה:
בכלב תיאור:This reasonably well-developed muscle lies under the skin on the medial aspect of the elbow
joint; it lies cranial to the M. flexor carpi radialis.
לא בהכרח שזה גם התיאור בסוס פשוט לא רשום.

Origin: Medial epicondyle of the humerus.
Insertion: Cranio-medial margin of the proximal radius.

Q

M.Extensor carpi radialis function dog vs big animals

A

Function dog: Extension of the carpus.
Flexion of the elbow.-ייתכן שתפקיד זה הוא גם בחיות גדולות פשוט דר לא התייחסה ובחוברת זה לא ברור
Function Horse: this muscle and the M. biceps brachii / Lacertus fibrosus play an important role in the passive support of the limb.

Q

M.Extensor carpi radialis discription dog vs big animals

A

Horse:
The Lacertus fibrosus joins the tendon of insertion in the distal half of the antebrachium.
Other species: the Lacertus fibrosus is of little or no consequence.

dog and big animals:
This powerful, fleshy muscle lies on the cranial aspect of the radius.
Just proximal to the carpus, the tendon of insertion is crossed by that of the M. abductor digiti I longus (M. extensor carpi obliquus), running from lateral to medial. The tendon of the M. extensor carpi radialis continues distally in the middle groove of the Trochlea radii and is held in place by the Retinaculum extensorium. The tendon of insertion is surrounded by a synovial sheath.
There may also be a bursa present beneath where they run onto the carpus.

לא לבוחן:
In the case of the horse, the synovial sheath
begins 80 - 100 mm proximal to the carpus and ends in the middle of the carpus. A bursa is
present just proximal to the point of insertion
