Direct Pathways (Corticospinal and Corticobulbar)
Precise and Voluntary Movements
Indirect Pathways (Rubrospinal, Vestibulospinal)
Programming Automatic Movements, Posture and Muscle tone, Equilibrium and Coordination of visual reflexes
White Ramus
Mylenated Axons
Dorsal Ramus
Sensory and motor innervation to the skin and muscles of the back
Gray Ramus
Unmyelenated axons that innervate glands and smoothe muscles
Ventral ramus
Supplying ventrolateral body surface, body walls and limbs
Area of skin supplied by one spinal nerve, overlap in case of damage, Sensory anestheia requires 3 spinal nerves to be blocked
Arterial Blood Supply
Branches from the Circle of WIllis on the base of the Brain
Epithelial cells
Sealed together by Tight Junctions
Incomplete BBB Barrier
Parts of the Hypothalmus, Pituitary Gland, Pineal Gland, Choroid Plexus
Proteins and Antibiotics
Not passed through the BBB
Concous thought Process, Memory storage and processing, Skeletal Muscle contraction
Thalmus (Part of Diencephalon)
Relay and processing centers for sensory Info
Hypothalmus (Diencephalon)
Centers conrtolling emotions, autonomic functions and hormone production
Processes visual and auditory data, reflexes, Maintenance of concousness
Relays sensory info to Cerebellum and Thalmus
Medulla Oblongata
Relays sensory info to the thalmus and other parts of the brain stem. Autonomic centers for regulation of visceral function.
coodinates complex somatic motor patterns, Adjusts output of other somatic motor centers in the bran and spinal cord
CSF Pathway
Travels through the lateral and medial aperatures to the subaracnoid space, Diffuses acros the aracniod granulatin into the superior sagital sinus
Reabsorbed throught the Arachnoid Villi
Has the Nuclei of 5 Cranial Nerves, Reflex centers for coughing sneezing swallowing
Medulla Oblongata
Olivary Nuclei
Relay information from the spinal cord, cerebral cortex, and brain stem to the cerebellar cortex
Medulla oblongata
Cranial Nerve Malfunction on the same side as body, irregularities in breathing and heart rythm
White fiber tracts ascend and descend. Pneumotaxic and Apneustic areas help contorl breathing.
Reticular Formation
Alerts Cerebral Cortex to sensory signals to awaken from sleep. Maintains Conciousness, keeps awake, and muscle tone.
Adjusts Posteral Muscles and tunes on-going movements
Anterior and Posterior Lobes
Govern subconcious aspects of skeletal muscle movement
Central consticted area of Cerebellum
Flocculonodular Lobe
Contributes to equilibrium and balance
Superior Colliculi of Mesencephalon
Reieves visual inputs from the lateral Geniculate nucleus of the Thalmus, Controls reflex movements of the eyes, head, and neck
inferior Colliculi of Mesencephalon
Recieves auditory data from the nuclei in the MO and pons, Controls reflex movements of the head, neck, and trunk
Substancia Nigra
Release the Neurotransmitter Dopamine in Mesencaphalon
Decrease in Dopamine levels
Increase in Muscle tone
RAS Headquarter
Involved in alertness and attentiventess
Plays a vital role in integrating conscious and unconscious sensory infor and motor commands. (Epi, Hypo and Thalmus)
Roof of 3rd Ventricle, contains pineal gland, Secretes Melatonin. Important to regulation of day and night cycle
Filter for Sensory info, projected into primary sensory cortex. Coordinates the activities of the cerebral cortex and nuclei, releys info between them
Circumventricular Organs
Monitors changes in blood Chem because no BBB. In the walls of 3 and 4 V's.
Controlssomatic motor activities at the subconscious level, autonomic functions, secretes hormones
Produces emotions and behavioral drives
