What does the nervous system rely on?
they rely on tiny cells called neurons
100
what does the nervous system consist of?
Brain, Spinalcord, and nerves
100
what is the central nervous system made of?
brain and spinal cord
100
what is the peripheral system made of?
nerves that branch off from the spinal cord.
100
Structure that plays a large role in processing new memories
hippocampus
100
This gland is located one on top of each kidney
adrenal gland
100
parathyroid
Controls calcium levels
100
These glands are found in the brain
pituitary gland , hypothalamus , pineal gland
100
The gland that connects the two hemispheres of the brain and allows for communication.
Corpus Callosum
200
what does PNS stand for?
peripheral nervous system
200
what does CNS stand for?
Central Nervous System
200
what does ANS stand for?
Autonomic nervous sysytem
200
What job does a dendrite do?
Gather Information
200
Helps control balance, muscle coordination, movement memory
cerebellum
200
What is the function of a hormone?
the body's chemical messengers, sending signals into the bloodstream and tissues.
200
Cope with physical and emotional stress; involved in "fight or flight" response
Adrenal Gland
200
Found in the pelvic cavity
testes and ovaries
200
What gland is also part of the digestive system?
Pancreas: produces enzymes that help to digest food, particularly protein
300
Two subdivisions of the Autonomic Nervous System
What is Parasympathetic Division- "rest and digest" and Sympathetic "Fight of Flight"
300
Name the five parts of a neuron.
cell body (soma)
dendrites
axon
myelin sheaths
axon terminals
300
What are the 4 main lobes?
1. Frontal
2. Parietal
3. Temporal
4. Occipital
300
what purpose does Myelin Sheath provide?
Allows information to travel more efficiently by insulating the axon and keeping the electrical signal in the axon
300
Controls basic life-support functions: breathing, circulation, swallowing
medulla
300
Creates T-cells that help in the immune system
Thymus
300
ovaries
menstrual and fertility hormones ; produce estrogen; repdroductive development
300
If you were to cut the body down the midline (midsagittal plane) from the throat down you would create two perfect halves of these glands (3)
thyroid , parathyroid , thymus
300
Olfactory Bulb
aids in sense of smell
400
The central nervous system is made of these organs
brain and spinal cord
400
What structure is not labeled on the diagram?
Mylen Sheath
400
What part of the brain serves as a relay station?
Thalamus
400
Name the two subdivisions of the Autonomic Nervous System and what is their function?
Parasympathetic: Calms the body; returns to a normal state; Rest and Digest
Sympathetic: Put your body's systems on alert; Fight or flight
400
Serves as the brain’s main sensory switchboard receiving info and directing it to the appropriate higher brain structure
thalamus
400
Thyroid
Growth and development and metabolism
400
Produce testosterone ; produce sperm ; reproductive development
Testes
400
Master Gland
Pituitary Gland
400
Why is the pituitary gland, know as the master gland?
It monitors and regulates many bodily functions through the hormones that it produces.
500
An action potential or the signal from the cell body travels along this
A neuron's axon
500
Relay impulses from the spinal cord to skeletal and smooth muscles, thus controlling all of our muscle movements
motor neurons
500
What are the neurons that take information from outside stimuli (temperature, pressure, pain) back to your brain?
sensory neurons
500
What is the function of the pineal gland?
secretes the hormone melatonin
500
Cerebrum
consist of two hemispheres which control emotion, hearing, vision and personality
500
Your metabolism is the process by which the body changes food and drink into energy.
If someone has a hypothyroid what are symptoms do you think they would exhibit?
slow movement
slow thoughts
weight gain (not burning energy but storing it)
500
A pancreas
secretes insulin and glucagon and digestive juices; blood sugar regulation , fat storage
500
Hypothalamus
Homeostasis - body temperature , hunger , thirst , fatigue , sleep
500
Cerebellum
body control and motor memory
