the name given to the quadriceps femoris tendon distal to the patella that helps provide stability to the stifle joint

Answer 2

patellar ligament

Question 3

the cartilaginous joint (amphiarthrosis) that unites the two halves of the pelvis ventrally; the pubic symphysis

Answer 3

pelvic symphysis

Question 4

the most proximal bony structure of the pelvic limb . Also known as the os coxae. Attaches to the sacrum dorsally at the sacroiliac joints and forms the hip joints with the heads of the femurs.

Answer 4

pelvis

Question 5

the bones that compose the digits

Answer 5

phalanges (plural) phalanx (singular)

Question 6

a depression in the dorsal surface of the sphenoid bone that houses the pituitary gland in the living animal

Answer 6

pituitary fossa

Question 7

a joint that allows only a rotary motion. Only true is the atlantoaxial joint between the first and second cervical vertebrae; also called a trochoid joint

Answer 7

pivot joint

Question 8

paired sesamoid bones in the legs of horses located in the large digital flexor tendons behind the fetlock joints

Answer 8

proximal sesamoid bones

Question 9

the smallest and most medial of the three pairs of bones that make up the pelvis and forms the cranial portion of the floor of the pelvis

Answer 9

pubis

Question 10

one of the two bones (other is ulna) that form the antebrachium, or forearm. It is usually the main weight-bearing bone

Answer 10

radius

Question 11

the hematopoietic (blood cell-forming) type of bone marrow

Answer 11

red bone marrow

Question 12

the most common type of bone marrow in adult animals. Consists mainly of adipose connective tissue. Does not produce blood cells but can revert to red bone marrow if the body needs greater than normal blood cell production

Answer 12

yellow bone marrow

Question 13

a joint movement that consist of a twisting motion of a part on its own axis

Answer 13

rotation

Question 14

the paranasal sinus in the sphenoid bone

Answer 14

sphenoidal sinus

Question 15

a ball and socket joint such as the shoulder or hip joint

Answer 15

spheroidal joint

Answer 16

splint bones

Question 17

the joint between the femur and the tibia. In humans it is the knee joint

Answer 17

stifle joint

Question 18

an immovable fibrous joint; for example, the sutures that unite most of the skull bones

Answer 18

synarthrosis

Question 19

viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates the joint surfaces

Answer 19

synovial fluid

Question 20

the membrane that lines joint capsules. Composed of connective tissue and produces synovial fluid, which helps reduce friction in the joint

Answer 20

synovial membrane

Question 21

the bones of the tarsus consisting of two rows of short bones located between the distal ends of the tibia and fibula and the proximal ends of the metatarsal bones

Answer 21

tarsal bones

Question 22

the joint composed of the tarsal bones; referred to as the hock in most animals and the ankle in humans

Answer 22

tarsus

Question 23

the main weight-bearing bone of the lower leg. It forms the stifle joint with the femur proximal to it and the hock with the tarsus distal to it

Answer 23

tibia

Question 24

a longitudinal ridge on the front of the proximal end of the tibia

Answer 24

tibial crest

Question 25

one bone pivots on another in a rotary motion. The only true pivot joint in the bodies of most domestic animals is the joint between the first and second cervical vertebrae

Answer 25

trochoid joint/ pivot joint

Question 26

one of the two bones (other is the radius) that form the antebrachium, or forearm. It forms a major portion of the elbow joint with the distal end of the humerus

Answer 26

ulna

Question 27

the process on the distal end of the distal phalanx of dogs and cats that is surrounded by the claw in the living animal

Answer 27

ungual process
