|---|
| neuron | the entire nerve cell |
| nerve cell body | all organelles, nucleus, translates the signal |
| axon | long strand of fiber coming out of cell body, carries messages to next nerve cell |
| dendrite | hair like - comes out of cell body, pick up signal from the axon of nerve next to it |
| synapse | space between the terminal end of the axon and the dendrite of the next cell |
| synapse jump | the electrical charge changes to chemical to jump across the synapse |
| myelin | fatty substace inside the schwann cell |
| schwann cell | cell that surround the axon filled with myelin to prevent electrical charge from straying outside the axon |
| conduction | movement of electrical charge through the axon of the neuron |
| sensory (afferent nerves) | carries impluses from sensory organs to the brain |
| sensory organs | all your senses, feel, taste, sight, hearing, smell |
| motor (efferent nerves) | carries messages from the brain to the muscles - allows you to react |
| interneruons | located in brain and spinal cord, the intrepret the messages and send the reaction message |
| cerebrum | largest part, emotions, controls voluntary functions, higher level thinking |
| cerebellum | balance, controls movement and coordination, |
| medulla oblongata | controls involuntary functions, breathing, digestion, heart beat, |
| brain stem | conects brain to spinal cord |
| hypothalmus | controls shivering, sweating, temperature, keeps us in homeostasis |
| pituritary | master gland of the body, relasese 85% of body hormones |
| right side brain | poetry, langague, art, creativity, |
| left side brain | math, logic, concrete reasoning, forming strategies, |
