The nerve net is the simplest form of a nervous system found in multicellular organisms.
What is the smallest nervous system?
The neuron is the smallest unit of the nervous system.
What is the nervous system for beginners?
The human nervous system comprises the brain, spinal cord, and peripheral nerves and is composed of several billion nerve cells or neurons. Specific populations of neurons, together with associated fiber tracts, are organized anatomically into pathways involved in sensory, motor, and cognitive function.
What is the smallest functional unit of nervous system?
The smallest functional unit of the nervous system is known as a neuron. A neuron is a specialized cell which transmits impulses. Its main function is to process and transmit information in the form of chemical or electrical signals. Neurons are the basic cells that make up the entire nervous system.

What is the smallest structural?
Cell: The cell is one of the basic principles of biology. It is considered as the smallest structural and functional unit of all living organisms.
What is the smallest unit of kidney?
Much of renal physiology is studied at the level of the nephron, the smallest functional unit of the kidney. Each nephron begins with a filtration component that filters the blood entering the kidney.
What is the junction of two neurons called?
Synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.
What is the smallest part of our body?
The cell. The cell is said to be the smallest part of the body which is alive. It is the structural and functional unit of life.
What is the 2nd largest part of the brain?
The cerebellum, the second largest portion of the brain, is located below the occipital lobes of the cerebrum. Three paired bundles of myelinated nerve fibers, called cerebellar peduncles, form communication pathways between the cerebellum and other parts of the central nervous system.
What are the 3 types of the brain?
The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain.
