Skeletal system review

List the function and the result or product of that function of the skeletal system

Support - Shape, alignment and positioning; Storage - Stores calcium, phosphorus + other minerals; Protection - protects structures; Movement - With muscles allows movement; Hematpoiesis - Blood formation

Three types of joints

Synarthrosis - No movement; Amphiarthrosis - Slight movement; Diarthrosis - Free movement

4 Types of diarthrosis joints

Ball and Socket - Shoulder and hip; Hinge - elbow and knee; Pivot - neck region; Saddle - thumb area

Difference between male and female skeletal systems

Male is generally larger, there is difference in hip orientation and shape

What socket is found in the innominate (hip) bone and what bones make it up?

Socket - Acetabulum; illium, Ischium & pubis

What bones make up the pectoral girdle

Clavical and Scapula

Three types of curvatures of the skeletal system

Kyphosis - exaggerated thoracic curve; Lordosis - exaggerated lumbar curve; Scoliosis - abnormal side to side

Main bones of the Axial skeleton

Skull, spine, chest, hypoid bone

Main bones of the Appendicular skeleton

Arms, legs, kneecap, clavicle, scapula

Whhat is the medical importance of growth plates

Allows medical professionals to know if a child is still growing

Describe the ways long bones grow

From the epiphyseal plate towards diaphysis; from the center of the diaphysis

Difference between the type of bone of the epiphysis and diaphysis

Epiphysis - Spongy bone; Diaphysis - Compact bone

Lacunae

Small pockets in lamella that house osteocytes

Osteoclasts

Destroy bone to make room for new growth

Osteoblasts

Bone forming cells

Types of osteocytes

Both are needed for normal growth and repair
