Brain Flashcards
Cerebellum
Coordinates and balances the actions of muscles
Cerebrum
Controls voluntary activities of the body
Brain stem
Regulates the flow of information between the brain and the body
Thalamus
Receives and relays messages from the sense organs
Hypothalamus
Controls, thirst, fatigue, anger and body temperature
Synapse
Where a neuron can transfer an impulse to another cell
Neurotransmitters
Chemicals used by a neuron to transmit an impulse across a synapse to another cell
Skeletal system that protects the central nervous system
Skull
Vertebrae
Spinal column
Connective tissues that protect central nervous system
Meninges
3 types of neurons
Motor
Sensory
Interneurons
Central nervous system consists of….
Brain
Spinal cord
Function of the nervous system
Controls and coordinates functions throughout the body
ADH
stimulates the kidneys to reabsorb water
FSH
stimulates production of eggs and sperm
LH
stimulates ovaries and testes
GH
stimulates protein synthesis and growth in cells
ACTH
Stimulates release of hormones from adrenal gland
Pineal
Melatonin/wake, sleep cycle
Thyroid
Thyroxine/regulates metabolism
Pancreas
Glucagon/ regulates blood sugar level
Thymus
Thymosin/ T cell development
Adrenal
Adrenaline/ flight or fight response, stress
Ovary
Estrogen/ female secondary sexual characteristics
Testis
Testosterone/ male secondary sexual characteristics
Reflex arc
- Stimulus
- Sensory cells/ receptors
- Sensory neurons
- Terminal branch meets dendrites of the inter neuron
- Spinal cord
- Motor neuron
