===='''Inner Pelvic Muscles'''====
===='''Inner Pelvic Muscles'''====
This set of muscles are a rather mixed group of small muscles lying close to the hip joint. They lie between the pelvis and trochantic fossa of the femur.
This set of muscles are a rather mixed group of small muscles lying close to the hip joint. They lie between the pelvis and trochantic fossa of the femur.
'''''Internal Obturator'''''
'''''Internal Obturator'''''
Only exists in carnivores and horses.
Function - extension of the hip and rotation of the femur laterally.
Origin and insertion - are both dependent on species involved.
'''''External Obturator'''''
'''''External Obturator'''''
Function - supinator of the femur and adductor of the limb.
Origin - the ventral pelvic surface close to the obturator foramen.
Insertion - trochantic fossa.
'''''Gemellus'''''
'''''Gemellus'''''
Function - rotation of the limb laterally.
Origin - ischiatic spine.
Insertion - unites partially with the internal obturator and so inserts on the trochantic fossa.
'''''Quadrate Muscle'''''
'''''Quadrate Muscle'''''
Function - extension of the hip and retraction of the limb.
Origin - ventral aspect of ischium.
Insertion - trochantic fossa.
'''''Articular muscle of the hip joint'''''
'''''Articular muscle of the hip joint'''''
Only in carnivores and horses.
Function - causes tension of the joint capsule and thus helps prevent damage to the peri-articular structures.
Origin - Hip joint capsule.
