Question

Who discovered nerve cells?

Answer 1

Hint: The nervous system, also known as the neural system, is a complex network of nerve cells or neurons. The nervous system is designed to carry messages, whereas the endocrine system uses hormones to provide chemical integration. The distinction between a neuron and a nerve is essential for a better understanding of the nervous system.

Complete answer:
In 1891, Heinrich Wilhelm Waldeyer coined the term "neuron" to describe the nervous system's basic functional unit. Purkinje cells were Johannes Purkinje's first nerve cells to be discovered.
Neurons are cells that have the ability to receive and transmit signals, and they make up the nervous system's core. They have a distinctive elongated shape and are made up of three parts:
Nerve cell body: The nucleus, endomembrane system, and organelles are all eukaryotic cell components.
Dendrites: Dendrites are tiny projections of the nerve cell body that branch out at the receiving end of the neuron. They function as mini-antennas, picking up signals from neighboring cells.
Axon: The axon is a long, thin fiber that extends from the body of the nerve cell. It branches out at the ends to form synaptic terminals marked by swellings known as synaptic knobs. Many axons are surrounded by a fatty myelin sheath formed by Schwann cells. The nodes of Ranvier are small gaps in the insulation found between the Schwann cells.

Thus, Heinrich Wilhelm discovered nerve cells.

Note:
Neurons, along with the glial cells that provide structural and metabolic support, are the primary components of the nervous system. The central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes the autonomic and somatic nervous systems, make up the nervous system.
