The CNS Flashcards
U4L8b (11 cards)
What are the Meninges?
The Meninges are three layers of tissue that ‘wrap-around’ the brain. They form the BBB which determines what chemicals could enter/exit the brain.
In between the layers, CSF can be found. It acts as a shock absorber, carries nutrients and provides connection between neural/endocrine systems.
What is the Cerebrum?
It is the largest/most developed part of the brain. It is what sets us apart from other species.
It consists of two hemispheres which are separate and have separate jobs.
They are connected via small bridge called Corpus callosum
What is the Cerebral Cortex?
It is the surface layer of the Cerebrum. It is divided into four regions.
Frontal Lobe
Temporal Lobe
Occipital Lobe
Parietal Lobe
What does the Frontal Lobe do?
The frontal lobe controls voluntary muscle movement and is linked to intellectual activities and personality.
What does the Temporal Lobe do?
The Temporal Lobe is responsible for vision/hearing.
It is also linked to memory and interpretation of sensory information.
What does the Parietal Lobe do?
Sensory areas; associated with touch and temperature awareness.
Also linked to emotions and speech interpretation.
What does the occipital lobe do?
The occipital lobe is associated with vision.
It also helps interpret visual information.
What is in the Hindbrain?
The Pons: Relay station that sends messages between cerebellum and medulla oblongata.
The medulla oblongata: centre of autonomic nerve control.
What is the cerebellum responsible for?
It is responsible for posture, balance and hand-eye coordination.
What is the thalamus responsible for?
The thalamus is responsible for interpreting sensory information and sending it to the cerebrum.
What is the left/right brain responsible for?
Left Brain: verbal, mathematical
Right brain: Artistic, musical, intuitive
