4 tissue types in the body
epithelial: covers the body, lines all cavities, composes the glands, at the surface. there are simple (one layer) and stratified (many layers)

connective: connects structures of the body, a "matrix" grounds the cells and is liquid, gel-like, solid,: contains fibers of collagen for strength and elastin for flexibility, an example is cartilage, blood and lymph are fluid connective tissue

muscular: provides movement and heat: skeletal, smooth, cardiac muscle

nervous:responds to env., detects, processes, coordinates information. two categories of cells: neurons and neuroglia (improve nutrient flow to the neurons)
connective tissue that is avascular (without blood vessels)
bone cells secrete osteoid substance that surrounds cells in an ossified matrix
there are little bumps on the skin that indicate where the adipose matrix is connected to the skin...where all say their fat is.
skeletal, smooth, and cardiac muscle
skeletal tissue is highly organized ( biceps and rectus)
smooth: lines hollow organs like blood vessels and digestive tract
cardiac muscle: facilitates the heartbeat by signalling for a contraction
neurons, nerves
carry electric impulses. dendrites recieve the projections and bring to the cell body. the other end of the neuron called the axon transmits impulses from the cell body to other cells.
nerves: clusters of neurons
peripheral nervous system:
nerves are part of it, in the body's periphery
central nervous system
central axis of the body
organization hierarchy
organ system
organism (ULTIMATE LEVEL): tries to maintain homeostasis
near the core of the body/fat from the core of the body
superior/inferior (based on what?_
above/below...based on anatomical position
cavities of body
ventral: belly area of torso

thoracic: chest area and houses the heart, lungs, vessels, and lymphatic system

abdominal: "guts"

pelvic: organs of the urinary system/reproductive system

dorsal: houses the brain

vertebral: houses the spinal cord
interstitial fliud, mediastinum
fliud that fills the spaces between cells of tissues, broad area between the lungs
biceps brachii, rectus abdominus
anterior muscle of the upper arm (bicep), "six pack" muscles
