Q

Outline ligaments

A

dense bands of CT attach bones to each other for support and strength

reinforce joints, flexible but strong end to end

collagen fibres like strains of a rope.

Q

condylar joints

A

oval surface depression, angular (2 planes)

17
Q

Hinge joints

A

back and forth (1 plane)

18
Q

Saddle joints

A

concave and convex on axes, angular, circumduction, NOT ROTATION

19
Q

Ball and socket

A

round end sits in cup depression, all movement

20
Q

Outline bone

A

osseous tissue with specialised cells and mineralised matrix

compact:
otuside, vascularised, calcified

spongy:
mineralised trabecular, avascular (mostly), surrounding marrow or adipose

21
Q

types of bones

A
short
flat
irregular
sesamoid
long
22
Q

short bone

A

cuboidal shaped, small boxy

23
Q

flat bone

A

thin, parallel surface, protection

24
Q

irregular bone

A

complex shapes

25
Q

sesamoid bone

A

sesame seed shaped, develop in tendon near a joint. protect tendons for wear.

26
Q

long bone

A

tubular shaped, slender

largest medullary cavities (bone marrow)

vascularised

site of growth

27
Q

parts of long bones

A

epiphysis:
ends of bone

diaphysis:
shaft, medullary cavity

metaphysis:
between diaphysis and epiphysis, epiphyseal plate

28
Q

what are epiphyseal plates

A

layer of hyaline cartilage at ends of growing long bones

new bone growth causing elongation

when finished, epiphyseal line

29
Q

what is a bony landmark

A

provide fixed point to determine position of joints and identify a bone.

30
Q

what is a tubercle

A

eminence often a site of tendon/ligament attachment. lesser or greater

tuberosity = larger
trochanter = femur
31
Q

what is a line/ridge

A

linear elevation often with a rough surface

32
Q

what is a foramen

A

passage/hollow part though a bone

33
Q

what is a condyle

A

knuckle like prominence for articulation

34
Q

what is an epicondyle

A

eminence superior or adjacent to condyle for attachments.
