Cells that bind the neurons together. Glial cells also provide an insulting covering (the myelin sheath) of the axon for some neurons, which facilitates the electrical impulse.
Cells in the nervous system that hold neurons together and help them communicate with one another.
Glial cells are kind of like honey in a bee hive. They keep the bees together on a task and the honey helps the bees communicate because they need to know what's going on and what to do.
The "master gland" that produces hormones influencing the secretions of all other endocrine glands, as well as a hormone that influences growth. The pituitary is attached to the brain's hypothalamus, from which it takes its orders.
Known as the "Master Gland" because it controls the hormone production of other gland.
It's kind of like the manager of a factory. He controls the production and he tells people when to send the product (hormones) out to people (or glands).
Drug or other chemical that enhances or mimics the effects of neurotransmitters.
A chemical that mimics the action of a neurotransmitter.
MDMA is a serotonin agonist.
Somatic nervous system
A division of the peripheral nervous system that carries sensory information to the central nervous system and also sends voluntary messages to the body's skeletal muscles.
Controls skeletal muscle as well as external sensory organs (skin). System under voluntary control.
When I want to pick up something, and I feel what it's like, the somatic nervous system sends a message to the skeletal muscles.
Autonomic nervous system
The portion of the peripheral nervous system that sends communications between the central nervous system and the internal organs and glands.
A subdivision of the peripheral nervous system. Controls involuntary activity and internal organs and glands.
Every time my heart beats or I breath unconsciously, that's my autonomic nervous system working.
The part of the autonomic nervous system that sends messages to internal organs and glans that help us respond to stressful and emergency situations.
Part of autonomic division; mobilizes the body in times of stress, danger or intense emotional arousal; "fight-or-flight" response.
One time I saw a very big spider in my kitchen and because of my sympathetic division, I began to run without even thinking about it.
The part of the autonomic nervous system that monitors the routine operations of the internal organs and returns the body to calmer functioning after arousal by the sympathetic division.
A division of the autonomic nervous system; it returns the body to its resting state
After I ran from the spider, I was able to calm myself down thanks to my parasympathetic division.
Drug or other chemical that inhibits the effects of neurotransmitters.
A drug that inhibits the activity of one or more receptors in the body. (AKA inhibitors)
An amino acid like GABA inhibits neurotransmitters and doesn't allow the activity to happen.
Bundle of nerve cells that follow generally the same route and employ the same neurotransmitter.
A group of nerve cells that send messages the same direction and employ the same neurotransmitters.
It's like, a student, who travels on the same route, on the same bus, with the same destination and the same purpose to go to school and learn.
The most primitive of the brain's three major layers. It includes the medulla, pons, and reticular formation.
Consists of pons, medulla and reticular formation; controls basic bodily functions such as respiration, blood pressure, & heart rate.
I always thought of the brain stem as the brain's connection to the spinal cord.
A brain-stem structure that controls breathing and heart rate. The sensory and motor pathways connecting the brain to the body cross in the medulla.
An extension of the spinal cord into the skull that coordinates heart rate, circulation, and respiration.
The is like the autonomic system of the brain stem instead of the nervous system.
A brain-stem structure that regulates brain activity during sleep and dreaming. The name pons derives from the Latin word for "bridge".
An area on the brain-stem that acts as a bridge between the medulla and other structures.
Pons are like the connection between two people. For example Lillie and I became friends because of a mutual friend. The mutual friend was the connection or pon.
A pencil-shaped structure forming the core of the brain stem. The reticular formation arouses the cortex to keep the brain alert and attentive to new stimulation.
A nerve network that travels through the brain stem and plays an important role in controlling arousal.
I can relate this to Lillie when I'm tired/unalert, Lillie is like the alert that wakes me up and gets my attention.
The brain's central "relay station," situated atop the brain stem. Nearly all the messages going into or out of the brain go through the thalamus.
Area of the brain that serves as a relay station for incoming sensory information.
This is like a relay race. The baton thing is like the message and the message has to go through a person.
The "little brain" attached to the brain stem. the cerebellum is responsible for coordinated movements.
Control of finely coordinated movements. Coordination center, voluntary movement and balance. "Small brain."
This part looks like a little brain, for example it when I type, the cerebellum is responsible for my coordinated finger movements.
The middle layer of the brain, involved in emotion and memory. The limbic system includes the hippocampus, amygdala, hypothalamus, and other structures.
A group of brain structures including the amygdala, hippocampus, basal ganglia, and hypothalamus. Associated with emotion and memory.
When I feel happy because of a fun memory, I know that the limbic system is involved in the process.
A component of the limbic system, involved in establishing long-term memories.
A neural center that is located in the limbic system; helps process explicit memories for storage.
When I had to remember the first time I met my best friend, I had to rely on my hippocampus to help me with my long term memory.
A limbic system structure involved in memory and emotion, particularly fear and aggression.
A brain structure involved in the arousal and regulation of emotion and the initial emotional response to sensory information.
One time my brother scared me at night and my emotions were mad and scared. This is because of my Amygdala.
A limbic structure that serves as the brain's blood-testing laboratory, constantly monitoring the blood to determine the condition of the body.
A structure found near the base of the forebrain that is involved in the regulation of basic biological needs.
For example, when I go to get my blood drawn once a month, they have to do blood tests in the laboratory, like the hypothalamus does inside body.
The thin gray-matter covering of the cerebral hemispheres, consisting of a 1/4-inch layer dense with cell bodies of neurons. The cerebral cortex carries on the major potion of our "higher" mental processing, including thinking and perceiving.
Is the cerebrum's outer layer of nerve cell bodies that covers the cerebral hemispheres and looks like gray matter.
It's like a thin blanket covering the brain and when I try to solve a word problem in math, the Cerebral cortex helps me.
