Thalamus |
Receives most of the sensory impulses from the body and distributes them to the special sense areas |
|
|
|
Hypothalamus |
Contains the heat regulating centre and is also concerned with hunger, thirst and emotional change |
|
|
|
Cerebrum - location and anatomy |
•Two large hemispheres • left hemisphere controls the right side of the body, right hemisphere controls the left side of the body |
|
|
|
Cerebrum - functions |
• motor areas which initiate the contraction of voluntary muscles • sensory areas which receive impulses from the skin, muscles, bones and joints • special sense centres dealing with sight, hearing, smell, taste and touch • centre of higher mental power - consciousness, memory, intelligence and reasoning • contains the thalamus and hypothalamus which control the autonomic nervous system |
|
|
|
Cerebellum - anatomy and location |
• underneath the posterior portion of the cerebrum |
|
|
|
Cerebellum - functions |
• balance • muscle co-ordination • muscle to e |
|
|
|
Brain stem - anatomy |
• mid brain • pons variolli • medulla oblongata |
Made up of three parts |
|
|
Mid Brain - functions |
• relay station connecting upper parts of brain and lower parts of brain and spinal cord • contains reflex centres affecting eyes, head and neck in response to visual or other stimuli |
|
|
|
Pons Varolii - anatomy and function |
Forms the link joining various parts of brain to one and other.
Joins the cerebrum above, through the mid brain to the medulla and cerebellum below |
|
|
|
Medulla Oblongata - anatomy |
The link between the brain and the spinal cord, joining the pons above to the spinal cord below. |
|
|
|
Medulla Oblongata - functions |
• contains the motor fibres which cross over controlling the opposite sides of the body • contains the respiratory, cardiac and vaso-motor centres • contains reflex centre which control the food and air passages and the reflex of sneezing, coughing, swallowing and vomiting |
|
|
|
What are the meninges? |
Three protective membranes surrounding the brain and spinal cord • Dura Mater • Arachnoid Mater • Pia Mater
Their function is to • maintain the brains position in the cranial vault • to protect the brim and spinal cord • absorb cerebrospinal fluid |
|
|
|
What is CerebroSpinal Fluid? And what does it do? |
• lubricates the brain and spinal cord • supports the brain • acts as a shock absorber • washes away waste and toxic substances |
|
|
