Week 4 - roadmap of the central nervous system Flashcards
(45 cards)
What comprises the Central Nervous System?
The brain and the spinal cord.
What does the Peripheral Nervous System do?
Connects the brain and spinal cord to the rest of the body.
What are the sub-systems within the Peripheral Nervous System?
The Somatic Nervous System and the Autonomic Nervous System (SNS and PNS).
Which two sub-systems comprise the Autonomic Nervous System?
The Sympathetic Nervous System and the Parasympathetic Nervous System.
Which system is responsible for increasing digestive activity?
The Parasympathetic Nervous System.
Which System is responsible for increased breathing, heartrate and arousal?
The Sympathetic Nervous System.
Which System is responsible for vegetative and non-emergency responses?
The Parasympathetic Nervous System.
Which system releases norepinephine?
The Sympathetic Nervous System.
Which system releases acetylcholine?
The Parasympathetic Nervous System.
What does Ipsilateral mean?
This refers to pathways that stay on the same side of the body
What does contralateral mean?
This refers to pathways that travel to the other side of the body.
What does a horizontal plane divide?
The upper and lower parts of the brain.
What does a Saggital plane divide?
It bisects the left and the right sides.
What does a Coronaplane divide?
The front (face) from the back (as seen from the front)
What does Dorsal refer to?
The Back (or top of the brain)
What does Ventral refer to?
The Belly (or bottom of the brain)
What does medial vs. lateral refer to?
The distance from the line running down our bodies. Medial is close to the line (ie. the nose) and Lateral is far (ie. the ears).
What parts comprise the Hindbrain?
Medulla, Pons and Cerebellum.
Which parts constitute the Brainstem?
The medulla and pons (midbrain) and certain central structures of the FOREBRAIN constitute the Brainstem.
What can be regarded as an extension of the spinal cord?
The medulla.
What do cranial nerves do?
They control vital reflexes such as breathing, heart rate, vomiting, salivation, coughing and sneezing.
Which parts are within the midbrain?
Superior colliculus, inferior colliculus, tectum, tegmentum, pineal gland
What is the reticular formation responsible for?
Volume control for the brain! Arousal.
Which part of the hind brain is responsible for sleep regulation?
the pons.
