APSM Biology Quiz 6
APSM CA Biology Quiz 6 3.1-3.3
| Term | Definition |
|---|---|
| addiction | when the body is desensitized to dopamine and needs more of a substance to get the pleasurable feeling |
| brain | principal organ of nervous system, chief organ of mind |
| brain stem | portion of brain the connects brain to spinal cord, includes 3 regions responsible for most automatic body functions |
| central nervous system | portion of the nervous system consisting of brain and spinal cord |
| cerebellum | Small part of the brain that coordinates your muscles |
| cerebral cortex | Outer layer of the cerebrum where all activity happens |
| cerebrum | portion of the brain that coordinates muscle activity |
| corpus callosum | mass of nerve fibers through which the cerebral hemispheres communicate |
| dopamine | neurotransmitter that makes us feel pleasure |
| left hemisphere | side of the brain dominant in language processing, logical reasoning, and analytical thinking |
| right hemisphere | side of the brain dominant in creativity, intuition, and the processing of visual & spatial information |
| spinal cord | thin bundle of nerve fibers within spinal cavity by which the brain communicates with the body |
| autonomic nervous system | portion of peripheral nervous system that controls heart and other internal organs |
| capsaicin | chemical in chili peppers that stimulates thermoreceptors |
| chemoreceptors | Sense tastes and smells |
| cochlea | coiled tube in inner ear that detects vibrations and send them to the brain |
| cones | cell in retina that detects colors |
| cornea | transparent structure that replaces the sclera at the front of the eye |
| hypothalamus | portion of the limbic system that controls the autonomic nervous system and endocrine system and is responsible for the physical effect of emotions |
| iris | front-most muscular portion of the uvea, which forms the colored portion of the eye and controls the size of the pupil |
| lens | portion of the eye that focuses the rays of the eye |
| mechanoreceptors | any of a group of sensory receptors responsible for sensations of touch, pressure, and muscle sense |
| motor nerve fiber | axon that carries impulses from the brain & spinal cord to muscles & organs |
| nociceptors | sensory neuron that responds to damaging stimuli by sending signals to the spinal cord and brain, pain receptor |
| pain receptors | any group of sensory receptors that consist of a bare dendrite activated by damage, or extreme heat, cold, mechanical stress |
| peripheral nervous system | portion of the nervous system that consists of nerves |
| photoreceptors | specialized cells in the retina that convert light into electrical signals, enabling vision |
| pupil | opening through which light enters the eye |
| reflex arc | nerve pathway controlling a reflex, allowing nerve impulses to bypass the brain for a speed response |
| retina | Part of the eye with the photoreceptors |
| rods | cell in retina that detects light of all colors |
| semicircular canals | Responsible for sense of balance |
| sensory nerve fiber | axon that carries sensory impulses to the spinal cord & brain |
| sensory receptors | specialized neuron that transmits information from the senses to the central nervous system |
| somatic nervous system | Controls voluntary movement |
| thermoreceptors | Sense the temperature |
| tympanum | thin, cone shaped membrane that transmits changes in pressure of sound; eardrum |
| umami | one of the basic tastes (savory), characteristic of broths and cooked meats |
| axon | long extension of neuron that relays nerve impulses from cell body to neurons |
| dendrites | short, branched extension of a nerve cell that receives impulses from neurons and conducts them toward the cell body |
| impulses | electrical charge that travels along the membrane of a neuron |
| myelin sheath | protective, lipid rich layer surrounding the axons of many nerve cells |
| neurons | nerve cells; have long fibers that branch out from their cell bodies |
| neurotransmitters | chemical released into a synapse to cause action in the receiving cell |
| synapse | Gap between nerve cells |
