intramembranous ossification endochondral ossification

Question 29

when bone replaces membranes, the ossification is

Answer 29

intramembranous ossification

Question 30

when bone replaces cartilage, the result is

Answer 30

endochondral ossification

Question 30

occurs rapidly and takes place in bones that are needed for protection, such as sutures of the flat bones of the skullcap, which are centers of growth in early bone development

Answer 30

intramembranous ossification

Question 31

much slower than intramembranous ossification, occurs in most parts of the skeleton, especially in the long bones

Answer 31

endochondral ossification

Question 32

- first center of ossification, occurs in the midbody area. - becomes the body in a fully developed bone - appear before birth

Answer 32

primary center

Question 33

This primary center of ossification in growing bones is called

Answer 33

diaphysis

Question 33

- appear near the ends of the limbs of long bones. - appear after birth

secondary center

Question 34

syntarthrosis amphiathrosis diathrosis

Question 37

types of joints (structural)

Answer 37

Question 38

immovable joint

Answer 38

synarthrosis

Question 39

joint with limited movement

Answer 39

amphiarthrosis

Question 40

freely movable joint

Answer 40

diarthrosis

Question 41

subclasses of fibrous joints

Answer 41

syndesmosis suture gomphosis

Question 42

subclasses of cartilaginous joints

Answer 42

symphysis synchondrosis

Question 43

lack a joint cavity. the adjoining bones, which are nearly in direct contact with each other, are held together by fibrous connective tissue

Answer 43

fibrous joint

Question 44

also lack a joint cavity, and the articulating bones are healed together tightly by cartilage. allow little or no movement

Answer 44

cartilaginous joint

Question 45

freely movable joints, most often found in the upper and lower limbs, which are characterized by a fibrous capsule that containssynovial fluid.

Answer 45

synovial joint

Question 46

this joint may allow end of the bones make contact but are completely separate and contain a joint space or cavity

Answer 46

synovial joint

Question 47

movement types of synovial joints

Answer 47

1. gliding (plane) joints 2. pivot (trochoid) joints 3. saddle (sellar) joints 4. hinge (ginglymus) 5. condylar (ellipsoid) 6. ball & socket (spheroidal) joints 7. Bicondylar joints

Question 48

permits the least movement, sliding motion between the articulating surfaces

Answer 48

gliding

Question 49

articular surfaces of ginglymi, or ginglymus joints, are molded to each other in such a way that they permit flexion and extension movements only. (bending)

Answer 49

hinge

Question 50

trochoid joint is formed by a bony, pivot-like process that is surrounded by a ring of ligaments or a bony structure or both. - allows rotational movement around a single axis.

Answer 50

pivot

Question 51

term sellar, describes this joint structure well in that the ends of the bones are shaped concave-convex and are positioned opposite each other

Answer 51

saddle

Question 52

occurs primarily in one plane and is combined with a slight degree of rotation at an axis at right angles to the primary plane of movement. - The rotational movement is limited by associated ligaments and tendons. - Flexion, extension, abduction and adduction.

Answer 52

condylar

Question 53

allows the greatest freedom of motion. - The distal bone that makes up the joint is capable of motion around an almost indefinite number of axes, with one common center. - the greater the depth of the socket, the more limited is the movement. - deeper joint is stronger and more stable.

Answer 53

ball and socket

Question 55

usually provide movement in a single direction. - permit limited rotation. - formed by two convex condyles, which may be encased by a fibrous capsule.

Answer 55

Bicondylar
