What are the functions fo the cerebralspinal fluid?
|
Maintain even pressure & Absorb shock
|
|
|
What are the components of cerebrospinal fluid?
|
1. Water
2. Glucose 3. Sodium Chloride 4. Protein 5. Some waste products, such as urea |
|
|
Dura Mater
|
Outermost Spinal meninx
"Tough mother" 1 of 3 layers that covers the brain and spinal cord |
|
|
Subdural Space
|
Space between the Dura Mater and the arachnoid mater. Contains Serous Fluid
|
|
|
Arachnoid
|
"Spider-like." Middle layer of meninges
|
|
|
Subarachnoid space
|
Cavity beneath arachnoid space that is filled with serous fluid
|
|
|
Pia Mater
|
"Tender mother." Innermost layer of meninges
|
|
|
What are the 3 primary divisions of the brain?
|
Forebrain (prosencephalon)
Midbrain (mecencephalon) Hindbrain (rhombencephalon) |
|
|
PROSENCEPHALON
|
Consists of cerebrum and is seperated in halves by the longitudinal fissure.
Controls motor & emotional processing. AKA FOREBRAIN |
|
|
MECENCEPHALON
|
Contains the ventral cerebral and alos conveys impules from the cerebral cortex to the pons & spinal cord. AKA MIDBRAIN
|
|
|
RHOMBENCEPHALON
|
(occipital area) Helps interpret visual input from occipital portion of the brain. Cerebellum is here, helps maintain body posture & balance. Cerebellum is the reflex center that coordinates skeletal movement. AKA HINDBRAIN
|
|
|
CEREBRUM
|
Makes up bulk of brain. Surface is made of gray matter. AKA TELENCEPHALON
|
|
|
DIENCEPHALON
|
Contains the thalamus and the hypothalamus
|
|
|
What does the Thalamus do?
|
serves as a relay center and functions in the integration of sensory information
|
|
|
What does the hypothalamus do?
|
Controls body temp. water balance, sleep, appetite, some emotions and both divisions of the autonomic nervous system
|
|
|
What two major structures make up the FOREBRAIN?
|
1. Cerebrum
2. Diencephalon |
|
|
CEREBELLUM
|
Shaped like a butter fly.
Located under the optical lobes and behind the pons & medulla. Made of white matter with gray just on the surface. Reflex center in charge of coordination |
|
|
MEDULLA OBLONGATA
|
Portion of the brain the continues down with the spinal cord.
Controls vital functions such as breathing, heart rate, blood pressure, swallowing and coughing |
|
|
PONS
|
Anterior end of medulla.
Relays impulses between the cerebrum & the cerebellum AND between the cerebrum and the medulla |
|
|
What is a hemisphere?
|
2 halves of a head
|
|
|
SULCUS
|
Shallow groove
|
|
|
FISSURE
|
Deep groove
Seperates the cerebrum into hemispheres |
|
|
LOBE
|
4 divisions of the brain
|
|
|
VENTRICLE
|
Cavities within the brain that are filled with cerebral-spinalfluid.
|
|
|
FRONTAL LOBE
|
Forms the interiro portion f each hemisphere.
Controls voluntary function, moods, agression, smell, reception & motivation |
|
|
PARIETAL LOBE
|
The middle division of each cerebral hemisphere that controls sensory functions such as pain, touch and tempurature interpretation
|
|
|
OCCIPTAL LOBE
|
Bottom, back portion of the head.
Receives and interprets visual input |
|
|
TEMPORAL LOBE
|
Controls hearing, smell, and taste
|
|
|
CENTRAL LOBE
|
Insula lobe. Hidden from view, deep into the lateral sulcus. Seperates the lobes
|
|
|
LONGITUDINAL FISSURE
|
Sepperates the cerebrum into right and left hemispheres
|
|
|
CENTRAL FISSURE/SULCUS
|
AKA FISSURE OF ROLANDO
Groove between the frontal and parietal lobes |
|
|
LATERAL FISSURE
|
Deep groove between the temporal lobe below and the frontal and parietal lobes.
|
|
|
CHOROID PLEXUSES
|
Tiny masses of specialized capillaries that secrete cerebrospinal fluid.
|
