verterbral arteries
-Mid brain
-Pons
-Medulla oblongata
-middle cerebral artery
-Lateral surface of frontal, parietal and temporal lobes
-medial surfaces of the frontal and parietal lobes
Inability to coordinate musclular movement due to cerebellar lesion
A temporary weakness or paralysis of the facial muscles due to 7th cranial nerve lesion---> leading to one side of the face to droop or become stiff
Supplied from 3 main branches of the vertebral artery
Diencephalon
1. Lateral ventricles
2. Third ventricle
3. Fourth ventricle
4. Subarachnoid space
5. Arachnoid villi or the dural venous sinuses (site of absorption)
Brain disorder that leads to shaking and stiffness
-difficulty with walking, balance and coordination
Brain stem
Diencephalon
-Frontal Lobe
-Parietal Lobe
-Occipital Lobe
-Temporal Lobe
Sulcus
Arachnoid villi of the dural venous sinuses
basilar - via the medial and lateral perforating arteries
Posterior cerebral artery
The middle cerebral artery
Hearing and balance (equillibrium)
Smell
Vision
Facial sensations and chewing
facial movement and taste
Swallowing, taste, saliva secretion, throat sensation
(Anything vague)- heart rate, motor of digestive system, dramatic effect of the heart beat slowing and decrease of blood pressure, respiratory rate, motor to the larynx
rotation/movement of the head and shoulders
Eye movement
Tongue movement
Eye movement and pupil reflex
-Sensory neurons
-Motor neurons
-Inter-neurons
-carry nerve impulses from receptor to the CNS
-have long dendrites and short axons
-Carry nerve impulses from the CNS to an effector (ex. Muscle or gland )
-Found completely within the CNS
-Provides a link within the CNS between sensory neurons and motor neurons
-Have short dendrites
-Long or short axons
-Dura Mater (outermost layer)
-Arachnoid (Middle thin and wispy)
-Pia Mater (Inner most layer)
-Cervical (8)
-Thoracic (12)
-Lumbar (5)
-Sacral (5)
-Coccygeal (1)
Acts as a pathway for impulses to be conducted between the brain and the spinal cord
Connects cerebellum to the rest of the brain
Most inferior positioned portion of the brain
-connects the brain to the spinal cord
Controls:
-Breathing
-Blood pressure
-Heart rate
-also allows passage of nerve fibers between brain and spinal cord
Regulation of:
-Body temperature
-Water balance
-Metabolism
-control of endocrine system
-Sex, thirst, pain, pleasure, food
-thalamus
-epithalamus
-hypothalamus
-metathalamus = responsible for secrestion of hormones
-coordinating voluntary movements
-maintains balance and equillibrium
-vision
Damage to the occipital lobe can result in permanent blindness
-Recieving and processing sensory input
-Language
-Hearing
-Learning -understanding anf responding
-Process feelings
-Thinking
-Memory
-Behaviour
-Movement
Gyri
Fissures
-dendrites
-axons
-cell body
-synaptic terminals
-Lightens the weight of the brain
-Stabilizing brain during head movement
-Nouurishment of the brain
-removes waste products (acts as lymphatics)
