Questions with Solutions
Central Nervous System - -The brain and spinal cord
- Peripheral Nervous System - -Links the CNS with the body's sensory
receptors, muscles, and glands
- Somatic Nervous System - -Enables voluntary control of muscles
- Automatic Nervous System - -Controls the glands and muscles of internal
organs. Functions non-conciously
- Sympathetic Nervous System - -Part of the automatic nervous system. It
arouses and expends energy
- Parasympathetic Nervous System - -Part of the automatic nervous system.
It calms and conserves energy
- Adrenal gland - -Produces epinephrine and nor-epinephrine for a flight or
fight response
- Pituitary gland - -Master gland that regulates other glands
- Thyroid gland - -controls metabolism
- Pancreas - -regulates blood glucose levels
- Testes and ovaries - -regulates the production of testosterone or estrogen
- frontal lobe - -What lobe is the arrow pointing at?
- occipital lobe - -What lobe is the arrow pointing at?
- parietal lobe - -What lobe is the arrow pointing at?
- temporal lobe - -What lobe is the arrow pointing at?
- medulla - -part of the brain stem that controls heartbeat and breathing
- pons - -part of the brain stem that coordinates movement
- thalamus - -routes sensory information to other brain areas
, - cerebellum - -nonverbal learning and memory, judging time, modulating
emotions, discriminating textures, and coordinating voluntary movement
- hippocampus - -critical to the formation of memories
- amygdala - -helps to process emotions, particularly emotion and fear
- hypothalamus - -monitors the body's internal states and sends messages
to the endocrine system
- association areas - -coordinate and integrate information
- pre-frontal cortex - -used in judgement, planning, personality, voluntary
attention, and inhibitory control
- corpus callosum - -band of neurons that connect the right and left
hemispheres
- left hemisphere - -language, calculations, literal interpretations
- right hemisphere - -perceptual tasks, making inferences, modulating
speech, self-awareness
- to speed neural impulses - -What is the primary function of a myelin
sheath?
- A tiny gap that separates the sending neuron's axon terminal from the
receiving neuron's dendrite - -What is a synapse?
- clean up after neural transmission (mop up excess neural transmitters)
insulate and guide neural connections
provide nutrients to neural cells - -What do glial cells do?
- sensory neurons - -gather information from the body and direct it to the
spinal cord/brain
- interneurons - -neurons in the brain and spinal cord that communicate with
each other and other types of neurons
- motor neurons - -neurons that send information from the brain to the
muscles, directing movement
- 1) The action potential travels down the axon of the sending neurons
2) The axon terminal releases the neurotransmitter into the synapse.
3) The neurotransmitter crosses the synaptic gap and binds onto the
receptor sites on the dendrite of the receiving neuron.
