The Nervous System Dr. Walid Daoud Assistant Professor

Anatomy of Nervous System 1- Central nervous system: 1- Central nervous system:. Brain. Brain. Spinal cord.. Spinal cord. 2- Peripheral nervous system: 2- Peripheral nervous system:. Cranial nerves: 12 pairs. Cranial nerves: 12 pairs. Spinal nerves: 31 pairs. Spinal nerves: 31 pairs

Functions of Nervous System The nervous and endocrine systems control and maintain homeostasis. 1- Sensory nerves: receive impulse from sense organs and transmit them to CNS. sense organs and transmit them to CNS. 2- Motor nerves: conduct impulse away from CNS to the organ of response. CNS to the organ of response. 3- Mixed nerves: contain both sensory and motor fibers. motor fibers.

Autonomic Nervous System It controls involuntary functions and consists of 2 antagonistic systems: 1- Sympathetic nervous system:. Origin: Thoraco-lumbar.. Origin: Thoraco-lumbar.. Catabolic function.. Catabolic function. 2- Parasympathetic nervous system:. Origin: Cranio-sacral.. Origin: Cranio-sacral.. Anabolic function.. Anabolic function.

Nervous Tissue 1- Neurons: 1- Neurons:. Functional cells of the nervous system.. Functional cells of the nervous system.. Responsible for impulse conduction.. Responsible for impulse conduction. 2- Neuroglia:. Supporting cells.. Supporting cells.. Do not transmit nerve impulse.. Do not transmit nerve impulse.. Capable of phagocytosis.. Capable of phagocytosis.

The Brain 1-Cerebrum: Sensory, motor areas, emotions and memory. Sensory, motor areas, emotions and memory.2-Cerebellum: Coordination of movement and equilibrium. Coordination of movement and equilibrium.3-Diencephalon.4-Thalamus. 5-Hypothalamus. 6-Brain stem: medulla, pons and midbrain.

Spinal Cord 1-Ascending tracts: They contain sensory nerves that transmit impulse upward. They contain sensory nerves that transmit impulse upward. 2-Descending tracts: They contain motor nerves that transmit They contain motor nerves that transmit impulse downward. impulse downward. 31 pairs of spinal nerves. 31 pairs of spinal nerves.

Meninges Cover and protect the brain and spinal cord: 1-Outermost coat (dura mater): fibrous and tough, beneath is the subdural space. tough, beneath is the subdural space. 2-Middle coat (arachenoid): subarachenoid space is filled with cerebrospinal fluid. space is filled with cerebrospinal fluid. 3-Innermost coat (pia mater): for nourishment of the underlying tissue.

Disorders of The Nervous System. Facial Palsy.. Cerebrovascular Disease (CVA).. Epilepsies.. Parkinson Disease.. Multiple Sclerosis (MS).
