RVT- Appendicular skeleton Flashcards
What is the cavity called on the scapula that attaches to the head of the humerus?
Glenoid cavity
What is the purpose of the Acromion and where is it located?
It is on the distal end of the spine of the scapula, it extends out over the joint
What is the name of the tubercle located next to the glenoid cavity?
Superglenoid tubercle that serves as an attachment site for the proximal end of the ‘biceps bronchi muscle’
Name the bones leading out of the scapula running distally
Humerus Radius / ulna Carpus Metacarpus Phylanges
What are the names of the point of muscle attachment on the humerus?
Greater and lesser tubercles
What part of the humerus attaches into the glenoid cavity of the scapula and what kind of ‘joint’ does this form?
The ‘Head’ of the humerus
Synovial joint
What condyle surfaces of the humerus attach to the radius and ulna?
Trochlea - articulates with the ulna
Capitulum - articulates with the radius
Are the epicondyles or the condyles the articular surfaces of the humerus?
Condyles
Epicondyle are not articular
What is another name for the antebrachium bones?
Radius and Ulna
What is the name for the ‘point of the elbow’ and what is its purpose?
Olecranon process
Site for tendon attachment of triceps brachii muscle
What is the attachment point for the humerus to the ulna?
Condyles of humerus to the Trochlear notch of ulna
Which bone is the weight bearing bone of the antebrachium?
Radius
What is the name of the attachment joint of the radius to the carpus?
Styloid process articulates with carpus
What do the anconeal and coronoid processes of the Ulna do?
They are on the dorsal and ventral sides of the trochlear notch
What is the name of the carpal bone that we can see sticking out of wrist?
Accessory carpal bone
What are the bones of the hind limb running distally from the dorsal aspect?
Femur Tibia Tarsus Metatarsus Phylanges
Where do the ox coxae and femur connect?
The head of the femur sits into the acetabulum of the ox coxae.
How do the head of femur and acetabula stay together?
The head of the femur attaches to the lunate surface of the acetabulum and is attached with the ‘ligament of the head of the femur’ that sits in the acetabular fossa.
Synovial joint
What is the name of the articular groove that contains the patella?
Trochlea
What is the name of the attachment point on the femur that the hip and thigh muscles attach to?
Trochanters ( Greater and lesser)
What are the fabellae?
Two small sesamoid bones in proximal gastrocnemius muscle tendons of dogs and cats
What is the main weight bearing bone of the lower limbs of hind leg?
Tibia
What does the fibula do?
Parallel to Tibia
Serves as a muscle attachment site
Non weight bearing
What is the bone that is the heel of the foot called?
Calcaneous
