Introduction
Nervous System of Birds

• You can hardly examine a histological sample of any kind without finding some sign of nervous tissue, for example, sections of myelinated or non-myelinated nerves, isolated neurons, encapsulated nerve-ends or perhaps a nervous plexus.
• The nervous system consists of neurons of many shapes and sizes, including its support elements, and is basically the same to all domestic animals.

Central Nervous System(CNS)

• At the central nervous system, there is a structural framework provided by neuroglial cells and their processes.
• Additionally, the meninges, formed by connective tissue, surround the brain and spinal cord, providing support and protection.

 

Brain

- Neurons and Glial Cells.

Brain

- Multipolar neuron

Cerebellum

• Cotex divided into 3 layers:
- Molecular
- Purkinge Cell
- Granulosa

 

Cerebellum

- Purkinge Cell

Spinal

- Gray and White Matter

 

Peripheral Nervous System(PNS)

• In the peripheral nervous system, there are no neuroglial cells and many components of the system are supported by connective tissue and special cells.
• For example, axons and bundles of axons of peripheral nerves are jointly compressed by the loose as well as dense connective tissue and the processes of neurons are supported by Schwann cells.
• Some selected examples of nervous system elements are present according to their typical appearance in histological preparations of various kinds.
