Anatomy Quiz- Skeletal System

Tendon

dense tissue that connects muscles to bones

Ligament

strong tissue that connects bone to bone and stabilizes jointed

sacrum

Cartilage

flexible tissue that protects your joints and bones

Joint

where 2 or more bones meet, allows flexibility

clavicle

humerus

ulna

radius

What are the pelvic and pectoral girdles apart of? Which of the two is sturdier and less mobile?

apart of the appendicular skeleton

pelvic is sturdier but less mobile

what are the 4 parts of the axial skeleton?

skull, vertebral column, chest, and ribcage

osteocyte

the bone cells that maintain healthy bone structure and release chemical signals

osteoblast

construct bones by calcifying them as they form

osteoclast

remodels bones by absorbing bone tissue

example of long bone and its function

femur; weight-bearing

example of short bone and function

carpals; hand and wrist movement

flat bone example and function

scapula; upper limb movement and stability

irregular bone example and function

hip bones; support and weight distrubution

synarthrosis

non-moving joint

amphiarthroses

slightly moving joint

diarthrosis

freely moving joint

gliding

when one flat bone surface glides or slips over another

Flexion

decreasing angle of joint

extension

increasing angle of joint

hyperextension

bending that goes beyond anatomical position

parietal

frontal

occipital

temporal

yellow

middle phalanges

purple

distal phalanges

2 types of synovial joints and the movement they allow

intercarpal and allows gliding

intertarsal and allows gliding

synovial

allows most movement and connect with dense connective tissue

process of bone remodeling

Osteocytes release chemical signals to tell osteoclasts

Osteoclasts release enzymes for resorption

Macrophages promote bone tissue

Osteoblasts come in and build new bone

point if attachment for pelvic girdle

sacroiliac joint

point of attachment for the pectoral girdle

the sternoclavicular joint

why do the pelvic girdles of females differ from those in male?

wider pelvis for the need of childbirth
