A&P Lab Practical 2 go Flashcards
axial skeleton
skull & vertebral spinal column
appendicular skleleton
limbs or appendages
hyaline cartilage
- forms the walls of the voice box
- articular cartilages
- connects the ribs to the sternum
- most effective at resisting compression
- most springy and flexible
- most abundant
fibrocartilage
- between the vertebrae
- meniscus in a knee joint
elastic cartilage
- supports the external ear
- epiglottis
long bones
- contain the least amount of spongy bone
- mostly compact bone
- longer than wide
- femur, phalanges
short bones
- cube-shaped
- contain more spongy bone than compact bone
- tarsals and carpals
flat bones
- thin and usually curved
- bones of the cranium (Parietal)
- sternum
sesamoid bone
- short bones formed within tendons
- patella
irregular bones
- verterbrae
Compact bone
- dense and smooth
- made up of osteons
spongy bone
- honeycomb structure
- made up of trabeculae
epiphysis
the end of long bones
- composed of a thing layer of compact bone that encloses spongy bone
Epiphyseal line
produced after the long bone has stopped growing
Diaphysis
shaft of the bone (midsection)
Medullary Cavity
contains yellow marrow in adult bones
Periosteum
fibrous membrane covering made up of dense irregular connective tissue
Haversian Canal
- know as the central canal
- carries blood vessels, nerves, and lymphatic vessels through bony matrix
Osteon
central canal and all the concentric lamellae surrounding it
Lamellae
layer of bony matrix around a central canal
Lacunae
site of osteocytes
Osteoblasts
bone-forming cells; secrete unmineralized bone matrix or osteoid
Osteocytes
mature bone cells
Parietal bone:
pair or nonpair
location
pair; sagittal left and right sides of the brain
Temporal bone:
pair or nonpair
location
pair; right and left side of the brain near the ears
