Structure and functional unit of nervous system is
-
Nephron
-
Cyton
-
Neuron
-
Axon
Neurons are the structural and functional unit of the nervous system. Each neuron consists of dendrites, axon, and soma. Dendrites are the small extension of nerve cells that receive signals from sensory receptors or other neurons. The long extension of the cell body of the nerve cell is called as axon that serves to conduct the nerve impulse away from the cell body. Cyton /soma is the metabolic center of the nerve cell where the metabolic contents are manufactured. It is not involved in nerve impulse conduction. A nephron is the anatomical and functional unit of kidney and thus is the part of the excretory system. Thus, the correct answer is option C.
The nervous system is formed of
-
Brain
-
Spinal cord
-
Nerves
-
All of the above
The nervous system is a collection of cells, tissues, and organs ( brain, spinal cord, nerves ) through which an organism receives information from its surroundings and then directs the organism to respond to the stimulus.
The organ that helps us to recall and analyse is
-
Muscles
-
Brain
-
Spinal cord
-
Nerve
The brain regulates an array of functions necessary for survival. The brain houses our mind and our memories. Most available evidence suggests that the functions of memory are carried out by the hippocampus and other related structures in the temporal lobe of the brain. The brain also helps in the analysis of various body functions.
A nucleated differentiated cell that has lost the power to divide is
-
Nerve cell
-
Kidney cell
-
Liver cell
-
Leucocytes
Which cells do not form layer and remain structurally separate?
-
Epithelial cells
-
Muscle cells
-
Nerve cells
-
Gland cells
Which of the following is the part of a neuron?
-
Axon
-
Cell body
-
Dendrite
-
All of the above
The primary components of the neuron are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that receive messages from other neurons), and synapses (specialized junctions between neurons).
The bulbous structure present at the terminal end of an axon is_______________
-
Synaptic vesicle
-
Synaptic knob
-
Dendrites
-
Schwann cell
A. Synaptic vesicle store various neurotransmitters that are released at the synapse.
B. Synaptic knob-The bulbous structure present at the terminal end of an axon.
c. Dendrites-also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.
D. Schwann cell -also called neurilemma cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons.
So, the correct option is 'Synaptic Knob'.
