Menengies
This is the deepest layer of menengies that is connected to the brain and spinal cord.
What is pia mater?
This neuroglia is responsible for removing pathogens and can sometimes travel to the PNS but is mainly in the CNS.
What is microglia?
This contains the cells nucleus and DNA as well as other organelles.
What is the cell body?
The brain can be divided into left and right these.
What are hemispheres?
This is the condition in which a nerve has action potential or as we say it is at rest.
What is polarization? Or polarized
This fluid is found in the subarachnoid space and is responsible for nutrient exchange, waste removal, shock absorbtion and is created by ependymocytes.
The most numerous, largest neuroglia that is responsible for creating the blood brain barrier by connecting to blood vessels and stopping any chemicals from entering the brain are these.
What are astrocytes?
These slender projections recieve stimuli and transmits the impulse towards the cell body.
What are dendrites?
This region known as the forebrain is the largest region and divided into lobes.
What is the cerebrum?
Thus is when a nerve recieves a stimulus and becomes active.
What is depolarization?
This middle layer is named after a spider because it is weblike.
What is arachnoid mater?
These CNS neurolglia create insulation known as myelin.
What are oligodenderocytes?
This fiber transmits signals or impusles away from the cell body.
What is the axon?
This region is connects to the spinal cord and while the mid brain and pons are relay stations the medulla oblongata is responsible for your autonomic reflexes and cardiovascular and vasomotor centers.
What is the brain stem?
This is the period of time that it takes before a nerve can recieve another impulse.
What is the refractory period?
This is the area where serous fluid is found and named for the menengies in which it is under.
What is the subdrual space?
Thesd PNS cells create myelin shesths to insulate the axon.
What are schwann cells?
These gaps between the myelin sheaths allow impulses to hop and speed up the transmission.
What are nodes of Ranvier?
This region is supposedly cauliflower shaped and it is the second largest region that controls voluntary movements and balance.
What is the cerebellum?
This is when the neuron is returning to its resting state.
What is repolarization?
What is the dura mater?
These line ventricles of the brain and spinal cord and secrete Cerebrospinal fluid (CSF).
What are ependymocytes?
The end of the axon where neurotransmitters are stored.
What is Synaptic Bulb (or vesicles)?
This region of the brain houses the thalamus, hypothalamus, pituitary and pineal glands and regulates consciousness and autonmic functions.
What is the diencephalon?
Thus pump helps to remove sodium from the cell and potassium back into the cell during repolarization.
What is the sodium potassium pum?
