Theory:

The nervous system is the key feature of the animal kingdom, which mainly indicates the intelligence of a species. Since intelligence is directly related to the organism's survival, the nervous system has many adaptations for an organism that can facilitate control and coordination.

The nervous system in rabbits consists of:
  1. Central nervous system (CNS)
  2. Peripheral nervous system (PNS)
  3. Autonomic nervous system (ANS)
The brain and spinal cord make up the central nervous system. Twelve pairs of cranial nerves and \(37\) pairs of spinal nerves make up the PNS. The sympathetic and parasympathetic nerves make up the autonomic nervous system (ANS).
 
The brain is located in the cranial cavity and is protected by three membranes:

Meninges of mammals brain
  • Outer dura mater
  • Inner pia mater
  • Middle arachnoid membrane
Sections of the brain:
The brain is divided into three sections:
  1. Forebrain (prosencephalon)
  2. Midbrain (mesencephalon)
  3. Hindbrain (hippocampus) (rhombencephalon)
  • A pair of olfactory lobes, cerebral hemispheres, and diencephalon make up the forebrain.
  • The corpus callosum is a transverse band of nerve tissue that connects the right and left brain hemispheres.
  • The optic lobes are located in the midbrain.
  • The cerebellum, pons Varolii, and medulla oblongata make up the hindbrain.
