Answer 4

a joint that can move freely in various planes

Question 5

based on function, joints can be divided into synarthrosis, amphiarthroses, diarthroses. What does synarthroses mean?

Answer 5

immovable joint in which two bones are connected rigidly by fibrous tissue

Question 6

based on function, joints can be divided into synarthrosis, amphiarthroses, diarthroses. What does amphiarthroses mean?

Answer 6

slightly moveable joint in which the surfaces of bones are connected by ligaments or cartilage

Question 7

synovial joints are the most freely moveable joints in the body …but also the weakest. Name the 3 types of movements possible at synovial joints.

Question 9

based on 6 joint categories - shape and structure

_______ joints have bones with articulating surfaces that are flat or slightly curved, allowing for limited movement

Answer 9

plane

Question 10

based on 6 joint categories - shape and structure

_______ joints consist of the rounded end of one bone fitting into a ring formed by the other bone to allow rotational movement

Answer 10

pivot

Question 11

based on 6 joint categories - shape and structure

_______ joints act like the hinge of a door; the slightly-rounded end of one bone fits into the slightly-hollow end of the other bone; one bone remains stationary

Answer 11

hinge

Question 12

based on 6 joint categories - shape and structure

_______ joints consist of an oval-shaped end of one bone fitting into a similarly oval-shaped hollow of another bone to allow angular movement along two axes.

Answer 12

condyloid

Question 13

based on 6 joint categories - shape and structure

_______ joints include concave and convex portions that fit together and allow angular movement

Answer 13

saddle

Question 14

based on 6 joint categories - shape and structure

_______ joints include a rounded, ball-like end of one bone fitting into a cup-like socket of another bone which allows the greatest range of motion.

Answer 14

ball and socket

Question 15

the tibiofibular joint can be classified under fibrous joints in terms of its structure. Name the sub-heading under which this joint falls…

Answer 15

syndesmosis (tip: Distal end of tibia and fibula for synDesmosis)

Question 16

give an example of where in the body synchondroses occurs (consider the structural classification of joints)

Answer 16

between the first rib and the sternum

Question 17

give an example of where in the body symphysis occurs (consider the structural classification of joints)

Answer 17

in pelvis

Question 18

which type of cartilage is seen in joints where synchondroses occurs?

Answer 18

hyaline

Question 19

which type of cartilage is seen where joints are symphisized?

Answer 19

fibrous

Question 20

how is hyaline cartilage nourished

Answer 20

by diffusion as it’s avascular (and has no nerves)

Question 21

what name is given to the disorder where a synovial joint’s volume becomes enlarged due to a build-up of synovial fluid

Answer 21

hydrops
