The Nervous System
Consists of the brain, the spinal cord, and the network of nerve cells radiating to every part of the body.
What is the Nervous System?
The large cap covering the top of the brain, where conscious thought and thinking happens.
What is the cerebrum?
A chemical that can diffuse in the fluid between the cells and cross the synapse. Can usually be naturally brought into balance by exercise, sleep, and spiritual practices.
What are neurotransmitters?
A common, mild traumatic brain injury, that is a result of a hard knock to the head, which causes a bruise to form on the brain. When repeated, the symptoms will often be more severe the second time.
What is a concussion?
Made up of glands, soft groups of cells, and hormones, the powerful chemicals that the glands produce.
What is the endocrine system?
A nerve cell that has a cell body, one axon, and many dendrites.
What is a neuron?
Responsible for controlling functions such as breathing, heart rate, blood pressure, swallowing, sleeping and waking.
What is the brain stem?
A tiny space between each sending neuron's axon and the receiving neuron's dendrite.
What is a synapse?
Characterized by pain, swelling and hypersensitivity to touch.
What is inflammation?
This needs iodine in order to make thyroxine, which increases the metabolic rate of cells.
What is the thyroid?
A neural message that passes through a sensory neuron, an association neuron, and a motor neuron and causes a muscle to contract with any thought.
What is a reflex?
Cauliflower shape near the nape of the neck, but still inside the bony skull. It refines muscle movement and coordinates balance.
What is the cerebellum?
Heightens alertness, pleasure, and appetite and helps with motor control.
What is dopamine and/or serotonin?
An interruption in the normal blood flow to the brain.
What is a stroke?
Makes insulin to control blood sugar levels.
What is the pancreas?
These nerves bring information toward the brain and spinal cord.
What is sensory nerves?
Acts as a relay station for messages going in (sensory) and out (motor) of the conscious centers in the cerebrum.
What is the thalamus?
Relieves pain.
What is an opioid?
An inflammation of the brain itself, usually from a virus passed through a mosquito bite.
What is encephalitis?
Located atop each kidney, produces several hormones but are best known for producing hormones released in response to stress in order to prepare the body for conflict: to either stand and fight or to run away.
What is the adrenal glands?
An insulation provided by tiny living cells that form what looks like bubble wrap around the axon of a neuron.
What is a myelin sheath?
Both receives and sends out hormones that stimulate other glands to produce hormones, this also senses changes in the blood so it can regulate body temperature, appetite, and thirst.
What is the hypothalamus?
Not the process of growing new brain cells instead, axons and dendrites of some association neurons form new networks with other association neurons, connecting up with cells they didn't connect with before.
What is learning new information?
An abnormal, excessive activity of the brain's neurons, often with no clear reason and you can do nothing to shorten this.
What is a seizure?
Located deep in the brain, between the 2 halves of the thalamus. This produces serotonin that promotes wakefulness and in darkness, produces melatonin which encourages sleep.
What is the pineal body?
