  • physiology - the scientific discipline that deals with the processes or functions of living things
  • atom - the smallest particle of an element
  • chemical - a form of potential energy resulting from positions and interactions among subatomic particles
  • Golgi appratus - a cell that was producing large amounts of lipoproteins (proteins combined with lipids)
  • mitochondria - organelles found within cells, which are responsible for generating most of the chemical energy needed to power the cell's metabolism.
  • plasma membrane - a thin layer of phospholipid molecules surrounding all cells
  • nucleus - the largest structure inside a eukaryotic cell; it contains genetic material called DNA
  • plasma membrane - is a selectively permeable membrane that separates the interior of all living cells from the outside environment
  • nucleus - is the largest component of a eukaryotic cell; it contains genetic material called DNA
  • ribosome - is a structure composed of RNA and protein molecules that serves as the site of protein synthesis
  • Endocrine glands - secrete hormones
  • Melanin - is produce by melanocytes
  • Dendrites - in a neuron, short, branching cytoplasmic extension that receives information and carry it to the cell body
  • Synapse - is a junction between two neurons or between a neuron and an effector cell (muscle or gland)
  • Axons - are long, slender extensions of nerve cells that transmit electrical impulses away from the cell body.
  • Neurotransmitter - is a chemical substance released at synapses that transmits signals across the gap between one neuron and another
  • Nervous system - controls all activities of the body
  • Schwann cells & oligodendrocytes - the neuroglial cells that form a myelin sheath around axons
  • Nodes of ranvier - gaps between segments of oligodendrocytes of between individual schwann cells
  • White matter of the central nervoud system - is formed by bundles of parallel axons with their myelin sheaths
  • Mechanoreceptors - the type of sensory receptors that respond to physical forces such as bending or stretching the receptor
  • Olfactory neurons - have dendrites that extend to the epithelial surface of the nasal cavity and have extremely long cilia on the dendrites which airborne molecules bind to
  • Endocrine system glands - may have function in addition to producing hormones
  • The pituitary gland - is the small gland that rests in the sella turcica of the sphenoid bone.
  • T3 (triiodothyronine) - binding to target tissues causes increases in metabolism, body temperature and normal growth.
  • Type 1 diabetes menitus - is caused by the secretion of too little insulin form the pancreas
  • Water - the major component of plasma
  • Arteries - carry blood away from the heat
  • Lymphatic tissue - has lymphocytes that divide and increase in number when the body is exposed to foreign substances
  • Chemical mediators of inflammation - can produce vasodilation, chemotaxtic attraction of phagocytes, increased vascular permeability, net movement of fibrin and complement from blood to o the extracellular fluid
  • Antigens - substances that stimulate adaptive immunity responses
  • Bacteria, pollen, and transplanted tissues are examples of foreign antigens
  • Bile is produced in river by hepatocytes
  • The nasal cavity is divided into right and left sides by the nasal septum
  • Antidiuretic hormone (ADH) - increases the permeability of the distal convoluted tubules and
    and collecting ducts to water.
  • Proximal tubule - the primary site of nutrient reabsorption in the neuron
  • the labia minora - thin, lingitudal folds that border the vestibule
  • Cyanosis - is cause by decreased oxygen content of blood
  • Jaundice - caused by collection of abnormal bile pigment of the skin
  • The function of the skeletal system include all of the following:
    • support and protection
    • movement and leverage
    • blood cell production
    • storage of minerals
