Lesson 6
This system is encased in bone, it includes the brain and spinal cord. The other system is not protected by bone and is outside the brain and spinal cord, but connects the central nervous system to limbs and organs.
Central Nervous System (CNS) and Peripheral Nervous System (PNS)?
This is the term for the cell body of a neuron
Soma?
These three structures work together to protect the spinal cord.
What are vertebrae, meninges, and cerebrospinal fluid (CSF)?
The number of cranial nerves in the human body.
What is twelve?
This system is known as the involuntary nervous system.
What is the autonomic nervous system?
Sensation, Response, and Integration
the basic functions of the nervous system?
These channels in nerve cells open because of physical distortion
What are mechanically gated channels?
This separates the temporal lobe from the other regions. It is also known as the lateral sulcus.
What is the transverse sulcus?
These neurons carry the first sensory signal from the periphery to the spinal cord.
What is the first order neurons?
This part of the atomic nervous system helps the body relax digest food and save energy.
What is the parasympathetic division?
This large part of the PNS is responsible for controlling smooth muscle and glandular tissues in the digestive system
Enteric Nervous System (ENS)
-70mV is the difference in charge across a resting membrane.
What is resting membrane potential?
These are the protective coverings of the brain and spinal cord.
What are the Dura mater, Arachnoid mater, and Pia mater?
This nerve helps you feel your face and chew your food.
What is CN V, trigeminal nerve?
This part of the atomic nervous system helps the body prepare the to fight or flight response.
What is the Sympathetic Nervous System?
These are considered Glial Cells.
Schwann, Oligodendrocyte, Astrocyte, Microglia, Ependymal
This change in a neuron's membrane potential makes the inside less negative. It often leads to an action potential.
What is depolarization?
This lobe is associated with auditory sensation.
What is the temporal lobe?
This neuron starts at the top and sends movement messages down to the body.
What is the upper motor neuron?
This common drug activates both the sympathetic and parasympathetic ganglion, it can also raise blood pressure and disrupt heart rhythm.
What is nicotine?
This group of nervous system disorders includes conditions Parkinson’s, Schizophrenia, Alzheimer’s, and depression.
Neurotransmitter-associated disorders
These are the chemical messengers that convey upstream information to downstream target cells.
What are neurotransmitters?
This disease targets the somatic motor neurons in ventral gray horn nuclei.
What is ALS (Amyotrophic Lateral Sclerosis)?
This reflex helps you pull your hand away after touching something hot.
What is the withdrawal reflex?
This hormone is released by the adrenal medulla to help the body respond to stress.
What is epinephrine? (adrenaline is also acceptable)
