Lecture 12 - Coxofemoral joint Flashcards
What is the cingulum?
os coxae - pelvis
What is the parts of the os coxae?
Ilium, pubis, and ischium
What is the stylopodium?
Femur - Thigh
What is the zeugopodium?
Tibia and fibula - Leg (crus)
What is the autopodium?
pes
What is the basipodium?
Tarsal bones - Tarsus (hock, ankle)
What is the metapodium?
Metatarsal bones - metatarsus
What is the acropodium?
phalanges - digits (toes)
Where does the head of the femur articulate in the hip?
Acetabulum of the os coxae
What movement happens at the hip joint?
Flexion - crainally; Extension - caudally
What movements happen at the joints below the hip?
Flexion - caudally; Extension - crainally
What is another name for extension at the foot?
Dorsiflexion
What is another name for flexion at the foot?
Plantarflexion
Why is the sacroiliac joints composite joints?
Incorporate fibrocartilaginous and synovial portions
What are the two parts of the sacroiliac joint?
Auricular surface and iliac tuberosity
What joint type is the auricular surface?
fibrocartilaginous
What joint type is the lilac tuberosity?
synovial
What are the ligaments in regards to the sacroiliac joint?
Ventral sacroiliac, dorsal sacrolilac, and sacrotuberous
What do the auricular surface and the iliac tuberosity make up what surface on the pelvis?
Sacropelvic surface
What type of joint is the coxofemoral joint?
Synovial joint
How does the femur connect to the acetabulum?
ligament of femoral head
What is the ligament of the femoral head a continuation of?
transverse acetabular ligament
What determines the degree of mobility in the hip joint?
shape of the femur head
What is the femoral a. a continuation of?
External iliac artery
What muscles in the hip help make up the femoral triangle?
Sartorius and pectineus
What runs through the femoral triangle?
Femoral a.
What is helpful about the femoral triangle?
Easy place to feel femoral pulse
What branches off the femoral a.?
Deep femoral, Saphenous, lateral circumflex femoral a.
What other arteries are continuations of the femoral a.?
Popliteal, cranial tibial, and dorsal pedal
What comes off the internal iliac a.?
Caudal gluteal a. - cranial gluteal a.
What happens with the gluteus superficialis in unglates?
part become incorparated within biceps femoris, sometimes the semitendinosus
Where does the tendon in obturator internus exit in horses and dogs?
passes over sciatic notch caudal to acetabulum
Where does the tendon of the obturator internus end in horses and dogs?
trochanteric fossa
What does the tendon of the obturatur internus do in other animals?
Exits through obturator foramen
Where is the articularis coxae?
On the capsule over the cranial aspect of the hip
What does the articularis coxae do?
Protect hip joint capsule from being nipped between femoral and acetabular surfaces during movement
What is different about the semitendinosus in the horse?
has a second origin from first two caudal vertebrae
Where does the branches that innervate the hindlimb come from?
lumbo-sacral plexus
What nerve innervates the gluteal muscles?
Cranial and cuadal gluteal nn.
What nerve innervates the deep gluteal and caudal thigh muscles?
Sciatic n.
What nerve innervates the medial thigh muscles?
Obturator n. (and femoral n. )
What is the origin of the sciatic nerve?
last 2 L and first 2 S spinal nn.
Where does the sciatic n. terminate?
In thigh, as common fibular and tibial nn.
What medial thigh muscles is NOT innervated by the obturator n?
Sartorius m.
From what structure does the obturator n. leave the pelvis?
Obturator foramen
Where does the obturator n. originate from?
L4-6 spinal nn.
What artery does the obturator n. travel with?
Medial circumflex femoral a.
