CNS disorders
Neuron classification
100
What is this part of the brain called?
The Frontal lobe
100
What are the three main functions of the nervous system?
Detection of changes in and outside the body/Integration of information from each of the senses/Coordination of muscles, organs, and glands.
100
What is the part labeled number 1 called?
Dendrites
100
What is a concussion, and what is the cause of it?
A concussion is a traumatic brain injury caused by an impact that is not absorbed by cerebrospinal fluid and damages the brain itself.
100
Where do sensory neurons receive information from?
The peripheral nervous system.
200
What does the temporal lobe control?
The frontal lobe controls the auditory, taste, and olfactory areas.
200
What are the two divisions of the central nervous system?
Brain and spinal cord.
200
What is the part labeled number 2 called?
Cell membrane
200
What CNS disorder occurs when there's a blood clot or ruptured blood vessel that interrupts blood flow to a specific part of the brain?
A stroke
200
What do Somatic receptors detect?
It detects information from the outside world.
300
What part of the brain controls your vision?
The occipital lobe.
300
The Peripheral Nervous System (PNS) is all the nervous tissue outside the brain and spinal cord. What are the two divisions of the PNS?
The afferent division (transmits information from the senses towards the brain.)
The different division (transmits commands to the muscles and glands from the brain.)
300
What is the part labeled number 3 called?
Cell body/soma
300
What is a CNS disease that causes a gradual loss of neuron cell bodies and synapses in the cerebral cortex?
Alzheimers
300
What do Visceral receptors monitor?
The visceral monitor conditions within organs such as the lungs, stomach, etc.
400
How many layers do the cerebrum have?
The cerebrum has 2 layers.
400
What division controls the “fight or flight” responses?
The sympathetic division.
400
What is the part labeled number 4 called? (circular thing that surrounds axon)
Mylinsheet
400
What is Encephalitis caused by?
It is caused by a foreign substance or a virus.
400
Where do motor neurons carry and deliver signals/information?
Motor neurons carry signals from the central nervous system to muscles or organs.
500
Out of the six regions of the brain, what is the largest region of the brain and what does it control?
The cerebrum is the largest region, controlling conscious thought, complex movements, and memory.
500
What division controls the “rest and digest” responses?
The parasympathetic division.
500
What is the part labeled number 5 called?
Synapse
500
What are the 12 pairs of nerves, mostly from the head and neck, that attach directly to the brain? And what is a disease than can affect this?
The Cranial nerves. Some disease is
- Peripheral and Central Facial Nerve Palsy.
- Trigeminal Neuralgia.
- Eye muscle paresis.
- Trochlear Nerve Palsy.
- Abducens nerve palsy.
- Lesions of the visual pathway.
500
What do Interneurons do?
It joins other neurons together.
