| CNS includes | brain and spinal cord |
| PNS includes... | nerves outside the brain and spinal cord |
| cranial nerves | 12 pairs of nerves that emerge from the spinal cord |
| spinal nerves | 31 pairs of nerves that emerge from the spinal cord |
| sensory information travels.. | to the brain |
| motor information travels... | away from the brain |
| neurons | highly specialized cells that make up the nervous system and carry its sensory and motor information |
| dendrites | bring nerve impulses into the cell body |
| axons | take nerve impulses away from the cell body |
| synapse | space where two neurons meet |
| neurotransmitters | chemical agents in the brain that help carry information across the synaptic cleft |
| mylin sheath | a coating around the axon which helps increase the speed at which an impulse travels across a nerve |
| meninges | three membranes that line the skull and enclose the brain and spinal cord |
| what are the 3 meninges | pia mater, arachnoid mater, dura mater |
| What are the 3 things that protect the CNS | Bone, meninges and fluid |
| cardiac center | controls the heart |
| vasomotor center | controls the blood vessles |
| respiratory center | controls breathing |
| cerebellum | regulates motor and muscular activity (coordination and balance) |
| cerebrum | thinking, problem solving |
| insular cortex | "5th lobe" involved in consciousness |
| parietal lobe | sensory and perceptual information, and comprehending oral and written language |
| temporal lobe | auditory perception, memory, speech * |
| heschl's gyrus | auditory cortex |
| wernicke's area | language comprehension |
| occipital lobe | visual information |
| what are the organization principles of the brain | interconnectedness, hierarchy, specialization |
| contralaterality | bodily sense are processed on opposite sides of the brain |
| spoken language involves | respiratin, phonation, articulation |
| parts of the upper respiratory system | trachea, larynx, oral cavity, nasal cavity |
| lower respiratory system | lungs, bronchi, alveoli |
| thorax | skeleton of the chest |
| pleura | thin sac that attaches to the inner side of the thorax and outer side of the lungs |
| primary muscles | involved in restful breathing |
| secondary muscles | forced inspiration |
| trachea | cartilage tube that runs from oral cavity to lungs |
| resonance | airflow's ongoing vibration as it moves through the pharynx |
| articulation | the act of manipulating airflow submitted by the phonatory system to create highly precise speech sounds |
| auricle | visible portion of outer ear |
| EAC | external auditory canal- conducts sound waves inward |
| tympanic membrane | serves as a loudspeaker |
| eustachian tube | serves as a pressure equalizing tube (PET) |
| 3 bones in the middle ear | malleus, incus, stapes |
| ossicular chain | 3 bones connected (vibrations are carried along as mechanical energy) |
| inner ear | fluid filled cavity that resides deep inside the temporal bone |
| 3 major cavities in the inner ear | vestibule, semicircular canal, cochlea |
| tonotopic organization | basilar membrane organized by frequency- high to low |
| 3 layers of the tympanic membrane | ectoderm, mesoderm, endoderm |
| 2 regions of the tympanic membrane | pars flaccida, pars tensa |
| impedance | the sensitivity in the fluid versus air and how well sound waves travel through it * |
