Neurology: Is the branch of medicine that dealing with diseases of the nervous system .

Nervous system divided into:
Central nervous system (CNS)
Peripheral nervous system (PNS)
Autonomic nervous system (ANS)

Structure of the neuron:

Introduction

Divisions of the CNS:

Intracranial ( Cerebrum, Brain stem & Cerebellum)
Spinal part ( Spinal cord & Cauda equina)

Cerebrum:

Composed of 2 cerebral hemispheres connected to:
Each other by corpus callosum
Brain stem by cerebral peduncles



Introduction

Each Cerebral hemisphere divided into
four lobes:
Frontal lobe
Parietal
Temporal
Occiptal


Introduction

Brain stem:
Formed of:
Midbrain
Pons
Medulla
Connected to:
Cerebral hemishphere by cerebral peduncles
Cerebellum by cerebellar peduncles
The brain stem contains:
Cranial nerve 3&4 (in midbrain)
Cranial nerve 5,6,7&8 (in pons)
Cranial nerve 9,10,11&12 (in medulla)


Introduction


Introduction

Cerebellum:

Behind the brain stem
Formed of: medline vermis & two cerebellar hemispheres
Composed of: outer grey matter & inner white matter
Hemispheres and vermis

Introduction

Cerebellar hemispheres are the two bilateral structres

Vermis is the unpaired midline structure between the two hemispheres


Introduction

Cerebellar peduncles

Superior peduncle connects cerebellum with midbrain

Middle peduncle connects cerebellum with pons
Inferior peduncle connects cerebellum with medulla oblongata


Blood supply and driange of the brain:
Blood supply of the brain through the circle of willis.
Blood drainage though deep and superfacial venous system (venous sinuses).
Ventricular system filled with CSF.
The brain envelope by meninges

Introduction



Introduction

Spinal cord

Inside spinal canal
End at lower border of L1
The lowest 3 segments = Conus
The above 4 segemens = Epiconus
Inner grey matter and outer white matter
Cauda equina
Lumbosacral roots collection fills the lower part of the spinal canal below L1



Introduction




Introduction

Peripheral nervous system

Anterior horn cells
Roots
Plexuses
Peripheral nerves
Motor pathway:

Introduction

Neuro mascular junction and muscle

Autonomic nervous system which divided into:

Symathatic

Introduction

Parasymathatic

Sensory Pathway
