Nervous System and Neurons

• Dendrons are short, branched parts arising from cell body or cyton. Dendrons are many in number. 
• Neurolemma is the outermost nucleated cytoplasmic layer of Schwann cells. It surrounds the axon of the nerve cell. 
• Neurofibrils are long, thin, microscopic fibrils that run in every direction in the cell body and also extend in axon and dendrites. 
• Axon is a long, thin hair-like processes coming out of the cyton of a nerve cell. 

Cyton is a cell body of the neuron containing a nucleus, cytoplasm.   
Synapse is a structure that allows a neuron to pass an electrical signal or chemical signal to another neuron. 
Axon is a long, thin, hair-like process arising from the cell body of the neuron. 
A neuron is the functional unit of nervous tissue. It contains cyton or cell body, long, thin hair like the process called axon and many short branches called dendrites. Therefore, option C is correct. 

Dendrite is a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body. A neuron is an electrically excitable cell that processes and transmits information through electrical and chemical signals. These signals between neurons occur via synapses, specialized connections with other cells. An axon is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body. Myelinated axons are known as nerve fibers. The function of the axon is to transmit information to different neurons, muscles and glands. A neutrophil is a type of white blood cell, a type of granulocyte, and a type of phagocyte. 

The neurotransmitter substance found between a motor neuron and a muscle cell is acetylcholine. In the autonomic nervous system, acetylcholine (ACh) is the neurotransmitter in the preganglionic sympathetic and parasympathetic neurons. ACh is also the neurotransmitter at the adrenal medulla and serves as the neurotransmitter at all the parasympathetic innervated organs. ACh is also the neurotransmitter at the sweat glands, and at the piloerector muscle of the sympathetic ANS. 

• The axon terminals are the end of axon fiber and located close to the dendrites of another neuron, forming a connection known as a synapse and allowing them to send messages from neuron to neuron with the help of neurotransmitter. 
• So, a nerve cell transmits it's impulse to another through its axons. 

In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron. Synapsis is the fusion of chromosome pairs at the start of meiosis. A cell junction (or intercellular bridge) is a type of structure that exists within the tissue of some multicellular organisms, such as animals. Cell junctions consist of multiprotein complexes that provide contact between neighbouring cells or between a cell and the extracellular matrix. Synapticula is one of the numerous calcareous processes which extend between, and unite, the adjacent septa of certain corals.

The myelin sheath of neurons provides them with an insulating covering. It allows rapid transmission of signals from the nervous system to the body and vice-versa. Any damage to the myelin sheath will cause hindrance and slowing down of the transmission of signals to the axons.

So, the correct answer is 'Action potentials would be conducted too slowly along the neurons'.

A unipolar neuron is a type of neuron, in which only one neurite or protoplasmic process extends from the cell body. Bipolar neuron is a type of neuron, which has two processes extending from the cell body. Pseudounipolar contains an axon, that has split into two branches, one branch runs to the periphery and the other to the spinal cord. A multipolar neuron is a type of neuron that possesses a single, long axon and many dendrites. The majority of the neurons are multipolar.

The dendrites are the short, cytoplasmic extension which is present in the sensory organs and are responsible for the reception of the electric impulse. The dendrite passes the electric impulse to the cell body which passes the impulse to the axon. The axon is the long cytoplasmic extension of the neuron. There are telodendrons which are present at the tail of the axons. These regions can release neurotransmitters which can help in the transmission of the impulse through the synapse to the next neuron.

In the nervous system, afferent neurons (otherwise known as sensory neurons), carry nerve impulses from receptors or sense organs toward the central nervous system.

Neurons are the structural and functional units of the nervous system, responsible for transmitting electrical and chemical signals.

Cyton, axon, and myelin are all components of a neuron. Intermedin is a hormone produced by the intermediate lobe of the pituitary gland, not a part of nervous tissue.

• The multipolar neuron is the neuron which has many dendrons and one axon.
• Multipolar neurons are the most common type of neuron. They are located in the central nervous system (brain and spinal cord) and in autonomic ganglia.
• Hence Multipolar neuron means The neurons which have many dendrons and one axon.
• So, the correct answer is 'with many dendrons and one axon'.
