Other cavities
Nasal, oral, middle ear, orbital, synovial
Integumentary
Skin hair nails - external body covering, synthesizes vitamin D, regulates temp, excretes salt and urea
Skeletal
Bones and joints - protects and supports body, bones are the site for blood cell formation
Muscular system
Skeletal muscles - allows locomotion, facial expression, produces heat
Nervous
Spinal chord, nerves, brain, sensory receptors - body control system
Endocrine
Adrenal, thyroid, pineal and pituitary glands and pancreas, thymus, ovary, testies - secretes hormones
Cardiovascular
Heart and blood vessels - transports and pumps blood
Lymphatic
Spleen, lymph nodes, thymus, red bone marrow - keeps body healthy and houses white blood cells
Respiratory
Nasal cavity, pharynx, larynx, trachea, lungs - keeps body supplies with oxygen and maintains acid base balance
Digestive
Oral cavity, esophagus, liver, stomach, intestines, rectus - breaks food down for nutrients, removes undigestible materials in form of feces
Urinary
Kidney, ureter, bladder, urethra - eliminates nitrogenous waste from body
Nucleus
Control center
Ribosome

Detox sac
Mitochondria
Powerhouse, energized atp
Centrioles
Direct mitotic spindles
Cytoskeleton elements
Internal scaffolding
Inclusions
Substance not part of metabolic machinery
Passive transport
High to low, no energy required
Active transports
Low to high, energy required
Diffusion
All cells, due to random movement of partials, concentration gradient
Filtration
only across capillary walls, pressure gradient
Osmosis
Movement of h2o, h2o follows solute
Cell cycle
Interphase (g1, s, g2) to prophase, metaphase, anaphase, telophase
Endocytosis
Pinocytosis - drinking, phagocytosis - eating, receptor mediated endocytosis - selective for cholesterol and iron
Functions of the skin
Protection, temp regulation, sensation, metabolic functions, blood reservoir, excretion
Keratinocytes

Sharp, slender, pointed projection
Process
Any bony prominence
Facet

Flexion, extension, hypertension, hyperflexion, abduction, adduction, circumduction, lateral and medial rotation, inversion, eversion, supination, pronation
Sprain v strain
Sprain - excess stretch or tear of ligament
Strain - muscle problem
Recruitment
Increase in number of sacromeres firing that produces an increase in muscle force
Isometric
Fixed length contraction, regardless of the amount of force generatesd
Isotonic
Changing length contraction with the same amount of force applied
Astrocytes
Most abundant, skeleton, connect to nutrient supply, control chem environment, help development and synapse formation
Microglial cell
Checks health and turns into phagocytes
Ependymal cell
