Term
| Monosynaptic reflex pathway |
|
Definition
| simplest type of neural pathway; like a knee jerk. this doesn't involve the brain. it's hard wired. |
|
|
Term
|
Definition
| connect various neurons withen the brain and spinal cord |
|
|
Term
|
Definition
| sense the environment (chemicals, light, sound, touch) and encode this information into electrochemical messages that are transmitted by sensory neurons. |
|
|
Term
|
Definition
| carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body. |
|
|
Term
|
Definition
| carry signals from the outer parts of your body (periphery) into the central nervous system. |
|
|
Term
|
Definition
| This main part has all of the necessary components of the cell, such as the nucleus (contains DNA), endoplasmic reticulum and ribosomes (for building proteins) and mitochondria (for making energy). If the cell body dies, the neuron dies. |
|
|
Term
|
Definition
| long, cablie-like projection of the cell, carries the electrochemical message (nerve impulse or action potention) along the length of the cell. |
|
|
Term
|
Definition
| covers certain types of axons, it's like a rubber insulator on a wire. it's made of fat |
|
|
Term
| What kind of axon would myeline usually be found on? |
|
Definition
| Motor and sensory neurons, the fat helps to speed transmission. |
|
|
Term
| Give two examples of non-myelinated neurons. |
|
Definition
|
|
Term
| Dendrite or nerve endings |
|
Definition
| small, branch-like projections of the cell make connections to other cells and allows neuron to talk with others, or perceive enviorment.[image] |
|
|
Term
| What do motor neurons look like? |
|
Definition
| Have a cell body on one end, the axon in the middle, and the dendrites on the other end. |

Term
|
Definition
| connect various neurons within the brain and spinal cord |
|
|
Term
|
Definition
| individual neurons linked together that form a net around the entire animal |
|
|
Term
|
Definition
| simple brains that consist of localized (close) collections of neuronal cell bodies |
|
|
Term
| Regardless of the animal, brains have what parts? |
|
Definition
| Brainstem, cerebellum, hypothalamus and pituitary gland, and cerebrum. |
|
|
Term
|
Definition
| Controls the reflexes and automatic functions, limb movements and visceral functions (digestion). |
|
|
Term
| What does the brainstem consist of? |
|
Definition
| Medulla, pons and midbrain. |
|
|
Term
|
Definition
| An enlarged portion of the upper spinal cord. |
|
|
Term
|
Definition
| a band of nerve fibers on the lower surface of the brain stem (links the medulla oblongata and the cerebellum with the upper portions of the brain) |
|
|
Term
|
Definition
| integrates information from the vestibular system that indicates position and movement; uses this info. to coordinate limb movements |
|
|
Term
|
Definition
| organs mediating the labyrinthine sense; concerned with equilibrium |
|
|
Term
| hypothalamus and pituitary gland |
|
Definition
| these control visceral functions, body temperature and behavioral responses such as feeding, drinking, sexual response, aggression and pleasure. |
|
|
Term
| What is the cerebrum also known as? |
|
Definition
| Cerebral cortex, or just the cortex. |
|
|
Term
| What does the cerebrum consist of? |
|
Definition
| cortex, large fiber tracts (corpus callosum) and some deeper structures (basal ganglia, amygdala, hippocampus). |
|
|
Term
| What does the Cerebrum do? |
|
Definition
| integrates information from all of the sense organs, initiates motor functions, controls emotions and holds memory and thought processes (emotional expression and thinking are more prevalent in higher mammals) |
|
|
Term
|
Definition
| Frontal Lobe, Olfactory Bulb, Temporal Lobe, Pons, Cerebellum. |
|
|
Term
|
Definition
| spinal cord, brainstem, diencephalon, cerebellum and cortex. |
|
|
Term
|
Definition
| Contains nuclei for regulating blood pressure and breathing, as well as relaying information from the sense organs that comes from the cranial nerves. |
|
|
Term
|
Definition
| Relay movement and position information from the cerebellum to the cortex. Also contains nuclei that are involved in breathing, taste and sleep. |
|
|
Term
|
Definition
| Link various sections of the brain involved in motor functions, (cerebellum, basal ganglia, cerebral cortex), eye movements and auditory control. |
|
|
Term
|
Definition
| relays incoming sensory pathways to appropriate areas of the cortex, determines which sensory information actually reaches consciousness and participates in motor-information exchange between the cerebellum, basal ganglia and cortex. |
