| Question | Answer |
|---|---|
| what covers the neurons, they prevent cross talk, protects it to keep it from having other things come that aren't supposed to be there | Glia |
| carries messages away from the cell; give out | Axons |
| carry messages to cell; bring in | Dendrites |
| gap between the axon and dendrites | synapse |
| carry info across synapse to neuron | Neurotransmitters |
| carries info between organs and central nervous system | Peripheral |
| automatic body functions what we don't think about doing, ex breathing | Autonomic |
| all body movements | Somatic |
| spinal cord and brain | Central |
| 3 types of neurons | sensory, motor, and interneurons |
| The brain is broken into two hemispheres, connected by | corpus callosum |
| center of involuntary actions, at the bottom of brain | Brain stem |
| monitors response to injury, blood pressure, reflexes (sneezing, laughing) | Medulla |
| watchdog for danger; alertness; sends messages to wake you up or to also turn down energy | Reticular activating system (RAS) |
| relay between cerebellum and cerebral cortex | Pon |
| responsible for movement or balance and also posture and indicating speed and direction | Cerebellum |
| emotions | limbic system |
| controls body temp, regulates pituitary gland, control center for rage, pleasure, hunger, sexual drive | Hypothalamus |
| relay between body and cerebral cortex; sends to spinal cord | Thalamus |
| ⅔ of the brain, has two hemispheres and 4 lobes covered by cerebral cortex | Cerebrum |
| Control right side of body and controls language, speech, and reading | Left hemisphere |
| Controls left side of body Identifies patterns; gets us back after a walk around the block Controls artistic, holistic thinking, and imagination | Right hemisphere |
| what does the frontal lobe do | motor, creativity, and emotional reactions |
| what does the temporal lobe do | hearing, music, understanding of speech, memories of nonverbal events, in the bottom near the brainstem |
| what does the occipital lobe do | vision, lower back area of the brain |
| what does the parietal lobe do | body sense, positioning like being able to balance, orientation/ knowing where you are, idea of pressure, heat/cold, pain and some reading and thinking, top back portion of brain |
| Chemical messengers that travel through the bloodstream, maintain growth and sexual development, handle metabolism | Hormones |
| organs and tissues that produce hormones | Glands |
| hypothalamus controls this gland, master gland bc its hormones trigger others | Pituitary gland |
| produces energy for the body/ metabolism, overactive thyroids make you feel jittery or nervous, underactive make you feel slow drowsy or depressed and can make you gain weight | Thyroid gland |
| control speed of body functions, people with high levels usually don't get fat | Metabolism |
| controls calcium used in bones, nerves function, muscle contraction, and blood clotting | Parathyroid gland |
| produces melatonin, linked to sleep-wake cycle | Pineal body |
| immune system, recognizes and destroys invaders to the body | Thymus gland |
| has a hand in metabolism and physical characteristics, produces adrenaline in response to fear, stress, and anger | Adrenal gland |
| produces insulin, controlling sugar levels in bloodstream | Pancreas |
| produce estrogen and androgen | ovaries/testicles |
