opening through which blood vessels, nerves, or ligaments pass

Question 3

Fossa

Answer 3

shallow depression

Question 4

Sulcus

Answer 4

furrow along bone surface that accommodates blood vessel, nerve, or tendon

Question 5

Meatus

Answer 5

tube-like opening

Question 6

Crest (Attachment point)

Answer 6

prominent ridge or elongated projection

Question 7

Epicondyle (attachment point)

Answer 7

typically roughened projection above condyle

Question 8

Line/linea (attachment point)

Answer 8

long, narrow ridge or border(less prominent than crest)

Question 9

Spinous process

Answer 9

sharp, slender projection

Question 10

Trochanter

Answer 10

very large projection

Question 11

Tubercle

Answer 11

variably sized rounded projection

Question 12

Tuberosity

Answer 12

variably sized projection that has rough, bumpy surface

Question 13

Condyle (forms joints)

Answer 13

large, round protuberance with a smooth articular surface at end of bone

Question 14

Facet (forms joint)

Answer 14

smooth, flat, slightly concave or convex articular surface

Question 15

Head (forms joints)

Answer 15

usually rounded articular projection supported on neck (constricted portion) of bone

Question 16

Joint

Answer 16

point of contact between two or more bones, cartilage and bone, teeth and bone

Question 17

Classification of joints (2)

Answer 17

structurally (presence of joint cavity, type of connective tissue in between), functionally (degree of movement permitted)

Question 18

Structural classification of joints (3)

Answer 18

fibrous, cartilaginous, synovial

Question 19

Fibrous joints

Answer 19

bones held together by dense irregular connective tissue (sutures

Question 20

Cartilaginous joints

Answer 20

bones held together by hyaline or fibrous cartilage (synchondroses, symphyses)

Question 21

Synovial joints

Answer 21

contain a synovial cavity contained within a connective tissue capsule

Question 22

Functional classification of joints (3)

Answer 22

synarthrosis- immovable joint
amphiartrosis- slightly moveable joint
diarthrosis- freely moveable joint

Question 23

Synovial joints features

Answer 23

large range of movement, articulating bones have articular cartilage and held together by ligaments, have synovial cavity with synovial fluid, have nerve and blood supply

Question 24

Bursae

Answer 24

sac-like structures filled with synovial fluid that cushions movement of one body part over another

Question 25

Tendon sheaths

Answer 25

tube-like bursae that wrap around tendons subject to a great deal of friction (knees, elbow, wrists, knuckles)
