Systems
This system consists of the brain and spinal cord
The Central Nervous System
This part of the neuron takes in messages from outside with chemical messages
The Dendrites
This part of the brain is wrapped around the very end of the spinal cord and handles involuntary movements like blinking, digestion, and breathing
The Pons
This is the master gland, it controls hormones and signals the body to start puberty
Pituitary Gland
This is the very human part of the brain where we do all our complex thinking, the very outer layer of the brain
The Cerebral Cortex
These chemicals, like testosterone and human-growth are spread through the body in the blood stream, controlled by the pituitary gland
Hormones
this long tail of a neuron carries the electrical signal all the way from the soma to the terminal buds
The Axon
This very end of the spinal cord is super important to keep you alive, it controls heartbeat and breathing!
The Medulla Oblongata
This brain part is important in causing the fear response and forming memories from emotional events. That's why Mr. J remembers so well when he was bit by a dog when he was a kid, it was scary!
The Amygdala
This lobe sits at the front of the brain and handles complex judgement, decision making, and motor movements
Frontal Lobe
This is the system of nerves that stretches out from the spinal cord and reaches the whole body, all the way to the very outside of the body, the tips of the toes
Peripheral nervous system
These are the chemical messages neurons use to communicate with each other
Neurotransmitters
This is the "little brain" at the very back of the brain, it mostly helps with movement, coordination, and muscle memory.
The cerebelllum
This seahorse shaped brain part helps create memories, and moves them from short term to long term memories
The Hippocampus
This lobe, at the very back of the brain, handles most of the visual information we receive with our eyes
The Occipital Lobe
This system sends messages slowly throughout the body using hormones
Endocrine system
This part of the neuron releases neurotransmitters into the synapse when it receives an electrical signal
Terminal Buds
This cup shaped part of the brain is the relay station for all information coming from the senses going to the rest of the brain
The Thalamus
Right below the thalamus sits this part that helps maintain homeostasis by regulating hunger, thirst, and body temperature
The Hypothalamus
This lobe is on the side of our brain, and handles everything we hear, from the opposite side ear of course!
Temporal Lobe
This system moves your skeletal muscles all around your whole body
Somatic nervous system
This neurotransmitter is released when a painful event occurs. It's main job is to dull the feeling of pain, and looks similar to morphene
Endorphins
This bundle of nerves travels through the medulla and pons, up into the thalamus, and helps us maintain alertness and wakefulness and filters stimuli
Reticular Formation
This part of the brain is cut in split-brain patients to relieve their epilepsy. It acts as a bridge between the two hemispheres of the brain
The Corpus Callosum
This region in the left frontal lobe is specific to creating speech. Without this part, we can't understand word written or spoken
