Nervous System is a uniquely designed organ system of our body. This presentation is highlighting over the cellular configuration of this system. Neurons & Neuroglia are the two main players of the system. Neuron is the structural & functional unit of the system, while, Neuroglia are the supporting elements. At the end of this presentation, the young learner would be able to recognize different cell types of the Nervous system & their exclusive function.
The nervous system is the part of an animal's body that coordinates its behavior and transmits signals between different body areas. In vertebrates it consists of two main parts, called the central nervous system (CNS) and the peripheral nervous system (PNS).
NERVE CELLS FINAL( NEURON AND GLIAL CELLS.pptx FOR NURSING STUDENTSWINCY THIRUMURUGAN
THE NERVOUS SYSTEM CONTAINS TWO MAIN TYPES OF CELLS.
A neuron is a nerve cell that is the basic building block of the
nervous system.
Neurons are the structural and functional unit of the nervous
system.
Neurons are specialized to transmit information throughout the
body.
They constitute the communication network of the nervous system and transfer electrical impulses between the central nervous system and sensory organs such as eye,ear.nose,tongue and skin.
There are Approximately 86-100 billion neurons in the brain.
DENDRITES
Dendrites are the tree-like branched structures that arise from the nerve cell body.
Apart from the main dendrite branches, dendrites may contain additional protrusions
known as dendrite spines.
The axon hillock is a specialized region from which the
axon extends.
The axon is a single elongated tubal structure that extends from the Axon Hillock.
Each neuron has a single axon that extends and branches at its end.
The inner most Plasma membrane around the axon is Axolemma.
Neurilemma is the plasma membrane of schwann cells .
The spaces/gaps between the Schwann cells are known as the nodes of Ranvier and they serve to propagate electrical signals along the axon.
The branched end of the axon is known as the axon terminal[arborization] and
branches at the middle of the axon is axon collaterals .
This is the distal part of the axon that comes in contact with other cells. Also called as terminal boutons.
This part of the axon is largely involved in the release of the neurotransmitter.The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus ,cytoplasm and organelles.
The cell body connects to the dendrites, and send information to the
axon depending on the strength of the signal.
The neuronal cytoplasm have the following
The Nucleus,
Nucleolus,
Endoplasmic Reticulum,
Golgi Apparatus,
Mitochondria,
Ribosomes,
Lysosomes,
Endosomes,
And Peroxisomes. A bipolar neuron is a type of neuron which has two extensions (one axon and one dendrite).
A multipolar neuron is a type of neuron that possesses a single axon and many dendrites (and dendritic branches), allowing for the integration of a great deal of information from other neurons.
TYPES OF NEURON:
A unipolar neuron is a type of neuron in which only one process called a neurite extends from the cell body. A pseudounipolar neuron is a type of neuron which has one extension from its cell body. This type of neuron contains an axon that has split into two branches; one branch travels to the PNS and the other to the CNS.They are three types of neurons based on the function as follows Sensory Neuron
Inter-Neuron
Motor Neuron
Interneurons are the central nodes of neural circuits, enabling communication between sensory or motor neurons and the (CNS).
Glial cells (named from the Greek word for "glue") are non- neuronal cells that
provide support and nutrition,
maintain homeostasis,
form myelin,
and participate in signal transmission.
THIS PRESENTATION IS UPLOADED TO HELP THE EDUCATOR OF MEDICAL, NURSING & ALLIE HEALTH SCIENCES TO TEACH THEIR STUDENTS ABOUT THE NERVOUS SYSTEM. IT WILL ALSO CREATE AWARENESS AMONG THE COMMON PEOPLE REGARDING NERVOUS SYSTEM.
This power point presentation was made for a second year lecture class of neuroanatomy. It was based on answers of different questions regarding neuroanatomy. The class was taken by Dr. Zobayer Mahmud Khan, Lecturer, Department of Anatomy, Sir Salimullah Medical College, Dhaka.
The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body.
The brain is what controls all the body's functions. The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.What Are the Parts of the Nervous System?
The nervous system is made up of the central nervous system and the peripheral nervous system:
The central nervous system includes the brain and spinal cord.
The peripheral nervous system includes the nerves that run throughout the whole body.How Does the Nervous System Work?
The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body.
Billions of neurons work together to create a communication network. Different neurons have different jobs. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body to allow muscles to move. These connections make up the way we think, learn, move, and feel. They control how our bodies work — regulating breathing, digestion, and the beating of our hearts.

Neurological system includes brain and spinal cord. It plays an important role in functioning of our body. Encephalitis is the inflammation of the brain. Causes include viral infections, infections from insect bites or an autoimmune reaction that affects the brain. It can be life-threatening or cause long-term complications. Treatment varies, but most people require hospitalization so they can receive intensive treatment, including life support.

the CNS on one side with the same part on the opposite side.
• Decussation: the criss-crossing of 2 fellow tracts in the middle line.
• Lemniscus: a band of ascending sensory fibres in the brainstem. It begins
from a decussation below & ascends to end in the thalamus above.
• Exteroceptive sensation: sensation from the skin (pain, touch &
temperature).
• Proprioceptive sensation: sensations from muscles, ligaments, joints &
fascia (position, passive movements & vibrations).
