placement / orientation sensor

proprioceptors

sense organ

an organ with receptor cells in it.

homeostasis

The body keeping internally stable despite exterior changes.

spine

releys infomation to and from the brain

effector

something that triggers a response by the nervous system

sensory neuron

exterior cell body

motor neuron

cell body at top

interneuron

cell body in middle

dendrites (root-shaped)

receive signal

axon terminal

releases signal (bulbed-shaped)

chemical that carries the electronic signals over the synaptic gap

neurotransmitter

broad term for all chemicals associated with the synaptic gap

neurochemical

the electrical signal going through the neurons

nerve impulse

where is the hypothalamus?

inside of brain

Where is the pituitary gland?

outer right of brian

where is the thyroid

throat (boombox)

Where is the pancreas?

yellow gun-shaped boi below liver

where are the adrenal glands

on top of kidneys

first?

electronic signal arrives at axon terminals of the presynaptic neuron

second?

neurotransmitters are released and pass the synaptic gap

third?

neurotransmitters bind to receptors on dendrites on postsynaptic neurons.

fourth?

The electronic signal travels down the postsynaptic neuron.
