Corona Radiata
Corona Radiata is a collection of nerve fibers present in the brain that carries messages between the brain cells of the cerebral cortex and the brain stem. Both brain stem and cerebral cortex play a role in motor function and sensation and it is the cor…
Neuron Structure
A neuron is defined as the functional unit of the body system called the nervous system. It is significant in transmitting signals that include receiving and sending the signals from a portion of the brain. The neurons are considered specialized cells in…
Afferent Neurons
Neurons are electrically excitable cells in the body specialized for receiving and transmitting information. They are referred to as the structural units of the nervous system. The important parts of a neuron include the cell body, dendrites, and axons.
Motor Homunculus
The term homunculus is Latin and is referred to as ‘little man’. In neuroanatomy, the cortical homunculus is either the motor or sensory distribution along the cerebral cortex of the brain. It was discovered by the great scientist ‘Wilder Penfield and Ed…
Nervous System
The nervous system is the portion of an animal's body that controls and transmits signals between various parts of the body. The central nervous system (CNS) and the peripheral nervous system (PNS) are the two primary components of the nervous system in …

Summary Introduction

To review:

About the ganglia and reason behind its accumulation in the anterior part of many invertebrates.

Introduction:

When the cell bodies of neurons get clustered together, then this cluster is called as the ganglia. The ganglia are required to process an information and pass it to the other cells. Even a small invertebrate like an earthworm or a spider needs ganglia to perform simple tasks.
