Nervous System
What way does information travel down a neuron?
Dendrites > cell body > axon > synapse
How does the Endocrine system send signals?
Through hormones produced by glands
What part of the neuron recieves signals from other neurons?
Dendrites
What is a function of the amygdala?
Fear, emotional memories, recognition of faces
What does the motor cortex control?
Voluntary movement
What does the autonomic nervous system link the CNS with?
Internal organs
What does GABA do?
Inhibitory transmitter, blocks other messages from reaching other NTs
What is one task that the neuron performs?
Receive info from other neurons
Carry info down its length
Pass info to the next neuron in line
What is a function of the hippocampus?
Spatial orientation
Learning
Memory
What does the sensory cortex do?
Registers and processes body sensations
What does the Somatic Nervous System link the CNS with?
Skeletal muscles
One of the Adrenal Glands, produces cortisol
Adrenal Cortex
What are the support cells in the brain called?
Glia
What is a function of the hypothalamus?
Maintains homeostasis, directs eating, drinking, and body temp. Helps govern the Endocrine system via the pituitary gland.
What is the hindbrain made up of?
Cerebellum, medulla, and pons
When the body enters fight or flight, every function of the body speeds up except what?
Digestion
What does the Adrenal Medulla produce in times of stress?
Epinephrine and Norepinephrine (adrenaline and noradrenaline)
Images of the brain using strong magnets to show the oxygen-rich blood flowing to different parts of the brain, signaling activity.
fMRI
What is a function of the Medulla?
Control heart rate
Blood pressure
Breathing
What parts make up the limbic system?
Amygdala, hippocampus, and hypothalamus
What is the chemical part of the nervous system?
Neurotransmitters
What is the role of the pituitary gland in the endocrine system?
Regulates growth and controls other endocrine glands
This neural imaging tool involves injecting the patient with a (safe) radioactive chemical and watching the blood flow. Usually used to detect cancerous tumors.
PET Scan
What is a function of the Pons?
Link between hindbrain and midbrain
Helps control breathing
Chemicals: sleep-wake cycle
What is a function of the parietal lobe?
Receives info from skin and body
Represents space/relationship to it
Includes the sensory cortex
