movable joint
a general type of joint that enables movement.
immovable joint
a general type of joint that allows little or no movement, like in the skull
homeostasis
process by which organisms maintain a relatively stable internal environment
stress
the reaction of the body and mind to everyday or threatening challenges and demands
ball and socket joint
joint that allows wide range of movement, like hip and shoulder joints

pivot joint
rotating joint for swiveling motion, like the neck
gliding joint
a joint that allows one bone to slide over another, like wrist and ankle
ligament
connective tissue that attaches bone to bone
cartilage
A connective tissue that is more flexible than bone and that protects the ends of bones and keeps them from rubbing together
dislocation
when a bone comes out of its joint
sprain
An injury in which the ligaments holding bones together are stretched too far and tear
fracture
a broken bone
x-ray
a way to see if bones are broken, by using waves of energy that pass through soft tissue, but not bones
skeleton

MRI
a way to show injuries to soft and hard tissues, by using magnetic fields and radio waves
arthritis
painful inflammation and stiffness of the joints
smooth muscle
involuntary muscle found in internal organs
cardiac muscle
involuntary muscle tissue found only in the heart.
skeletal muscle

top layer of skin
dermis
inner layer of skin
involutary muscle
muscle that can't be consciously controlled
voluntary muscle
A muscle that is under conscious control
muscle contraction
when a muscle shortens
skin
largest organ of the body that provides protection, regulates temperature, eliminates wastes, gathers information, and produces vitamin D
melanin
a pigment in the epidermis that gives the skin its color
pore
an opening in the dermis for sweat to reach the surface of the skin.
follicle
structure in the dermis of the skin for hair to grow
keeping skin healthy
healthy diet, cleaning, limit sun exposure
major functions of the skeletal system
support, protection, movement, storage of minerals, blood cell production
compact bone
hard, dense bone tissue that is beneath the outer membrane of a bone
spongy bone
layer of bone tissue that has many small spaces and is found just inside the layer of compact bone
bone marrow
a soft tissue inside the bone that produces blood cells and stores fat
osteoporosis
a condition in which the bones become fragile and break easily
cancer
a disease in which some body cells grow and divide uncontrollably, damaging the parts of the body around them
tendon
connective tissue that connects muscle to bone
