Chapter 7 Vocab Set 190-217 Flashcards
a space within the skull bone that is an outpouching of the nasal cavity. Depending on the species, they are found within the frontal, maxillary, sphenoid, and ethmoid bones
paranasal sinus
the name given to the quadriceps femoris tendon distal to the patella that helps provide stability to the stifle joint
patellar ligament
the cartilaginous joint (amphiarthrosis) that unites the two halves of the pelvis ventrally; the pubic symphysis
pelvic symphysis
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.
pelvis
the bones that compose the digits
phalanges (plural) phalanx (singular)
a depression in the dorsal surface of the sphenoid bone that houses the pituitary gland in the living animal
pituitary fossa
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
pivot joint
paired sesamoid bones in the legs of horses located in the large digital flexor tendons behind the fetlock joints
proximal sesamoid bones
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
pubis
one of the two bones (other is ulna) that form the antebrachium, or forearm. It is usually the main weight-bearing bone
radius
the hematopoietic (blood cell-forming) type of bone marrow
red bone marrow
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
yellow bone marrow
a joint movement that consist of a twisting motion of a part on its own axis
rotation
the paranasal sinus in the sphenoid bone
sphenoidal sinus
a ball and socket joint such as the shoulder or hip joint
spheroidal joint
the vestigal metacarpal and metatarsal bones of a horses’ leg. There are two splint bones in each leg: one on each side of the cannon bone (large metacarpal or metatarsal bone)
splint bones
the joint between the femur and the tibia. In humans it is the knee joint
stifle joint
an immovable fibrous joint; for example, the sutures that unite most of the skull bones
synarthrosis
viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates the joint surfaces
synovial fluid
the membrane that lines joint capsules. Composed of connective tissue and produces synovial fluid, which helps reduce friction in the joint
synovial membrane
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
tarsal bones
the joint composed of the tarsal bones; referred to as the hock in most animals and the ankle in humans
tarsus
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
tibia
a longitudinal ridge on the front of the proximal end of the tibia
tibial crest
