| Term | Definition |
|---|---|
| what are the functions of the skeletal system | Support, movement, mineral and lipid storage, homeopoises |
| 3 factors affect bone growth | stress, hormones, nutrition |
| 2 major types of skeletal bone growth | intramembranous ossification and endochondral ossification |
| 3 types of muscle | smooth, cardiac, skeletal |
| what is skeletal muscle | moves bines directly or indirectly, voluntarily controlled and striated |
| what are the characteristics of life | responsiveness, conductivity, respirations, digestion, absorption, secretion, excretion, circulation, reproduction |
| what are atoms? | tiny little spheres of matter |
| what are molecules | combo of atoms that form large chemical groupings |
| 4 major tissue types | epithelial, connective, muscle and nervous |
| what are the 4 body cavites | dorsal, ventral, thoracic, pleural |
| atomic mass | number of protons and neutrons in the atoms nucleus |
| atomic number | number of protons in the nucleus |
| isotopes | atoms that have same number of protons but different numbers of neutrons |
| metabolism | all chemical reactions that occur in the body |
| catabolism | chemical reaction that breaks down large food particles into smaller ones releasing energy |
| anabolism | chemical reactions that build larger more complex chemical molecules with energy. |
| hydrolysis | occurs during catabolism, water is added to and energy is released. |
| dehydrations synthesis | key reaction in anabolism and water is removed. |
| organic compound | contains carbon. has covalent bonds |
| inorganic compounds | water, oxygen |
| 4 major groups of organic substances | carbohydrates, lipids, proteins, nucleic acid |
| 3 types of carbohydrates | mono, dia, polysaccharides |
| classes of lipids | phospholipids, steroids, prostaglandins |
| proteins contain what elements | carbon, oxygen, hydrogen, nitrogen |
| DNA | pentose sugar (deoxyribose) nitrogenous base and phosphate group |
| RNA | contains RIBOSE sugar |
| bases in DNA | adenine, thymine, guanine, cytosine |
| bases in RNA | adenine, guanine, cytosine, uracil |
| role of PASSIVE transport processes | simple diffusion, facilitated diffusion, osmosis, and filtration |
| simple diffusion | molecules dissolves directly through membrane. |
| facilitated diffusion | requires transport proteins can be channels or carriers |
| osmosis | transport water form low to high |
| ACTIVE transport process | comes from the cell itself, energy of metabolism must be used to move particles across membrane *uses energy |
| endocytosis | plasma membrane traps some extracellular material and brings into cell |
| phagocytosis | engulfed by the plasma membrane |
| functions of the cerebral cortex | attention, perception, awareness, thought memory, language, consciousness |
| hypothalamus functions | mind-body link, maintain water balance, endocrine functions, release HGH and sex hormone, regulate appetite, arousal and alert state maintain body temp |
| name the 12 cranial nerves | olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, verstibulocochlear, glossophayngeal, vagus, accessory, hypoglossal |
| 3 functions of a neuron | afferent, efferent, interneurons |
| afferent | sensory neurons |
| efferent | motor neurins |
| interneurons | conducts impulses from afferent to efferent |
| classifications of a neuron | multipolar, unipolar, bipolar |
| membrane potential | difference in electrical charge across the plasma membrane |
| resting membrane potential | neuro not conducting electrical signals is resting |
| excitation of neuron | stimulus triggers the opening of stimulus gate NA+ channels |
| depolarization | movement of membrane potential to zero |
| preganglionic neuron | conduct impulses from the brainstem or spinal cord to an au-tonomic ganglion, |
| postganglionic neuron | conducts impulses away from the ganglion and to the effector |
| the sympathetic division has also been called | thoracolumbar division |
| white ramus | split away from other spinal nerve fibers by means of a small branch |
| gray ramus, | Some postganglionic axons return to a spinal nerve by way of a short branch |
| the parasympathetic division has also been called | craniosacral division |
| Axon terminals of autonomic neurons release either of two neu-rotransmitters | norepinephrine (NE) or acetylcholine (ACh) |
| Axons that release NE | adrenergic fibers. |
| Axons that release ACh | cholinergic fibers. |
| The adrenergic receptors are of two main types, | alpha (␣) receptors and beta () receptors |
| The actions of NE and epinephrine are terminated in two ways. | Most of the neurotransmitter molecules are taken back up by the synaptic knobs of postganglionic neurons, where they are broken down by the enzyme monoamine oxidase (MAO). the remaining neurotransmitter molecules are eventually broken down by another enzy |
| The two main types of cholinergic receptors | nicotinic (N) receptors and muscarinic (M) receptors |
