Brain Anatomy and Nervous System Flashcards
Name the 4 parts of the brain
Cerebrum
Cerebellum
Diencephalon
Brain Stem
What is the role of the Cerebrum?
Largest part of the brain that controls thought and perception.
What is the role of the Cerebellum?
Motor control and movement.
What are the three parts of the Diencephalon?
Thalamus
Hypothalamus (homeostasis)
Pituitary Gland (Secrete hormones)
What are the three parts of the brain stem?
Pons
Medulla Oblongata
Midbrain
What are meninges? What are the three layers of the meninges, from outer to inner?
Cover the brain and the spinal cord.
Order: Dura mater > Arachnoid > Pia mater
What flows between the layers of the meninges?
Cerebrospinal fluid
How many pairs of cranial nerves are there? Where do they originate?
- Originate in the brain.
How many pairs of spinal nerves are there? Where to they originate?
- Originate in the spinal cord.
What separates circulating blood from the fluid in the CNS? What is it’s function?
The blood-brain barrier. Prevents toxins from getting in the brain.
What are the two types of cells in the nervous system?
Glial cells and neurons
What is the function of glial cells? Which glial cells are found in the CNS? The PNS?
Glial cells help protect the nervous system. Oligodendrocytes are found in the CNS. Schwann cells are found in the PNS.
Which aspect of the nervous system is responsible for the “Fight or Flight” response? What are its neurotransmitters?
Sympathetic nervous system. Adrenergic/catecholamine/epinephrine
Which aspect of the nervous system is responsible for the “Rest and Digest” response?
Parasympathetic nervous system. Cholinergic/acetylcholine
What does SLUD stand for?
Salivation
Lacrimation
Urination
Defecation
