Question

All information from our environment is detected by the specialized _______ cells.
A) Nerve
B) Nephron
C) Glial
D) Companion

Answer 1

Hint: The central nervous system is in charge of the majority of bodily and mental processes. It is divided into two sections: the brain and the spinal cord. The brain is the center of our emotions, the translator of our environment, and the source of body movement control.

Complete answer:
Neurons/nerve cells and neuroglia/glial cells are the two major groups of cells in the nervous system.
A) Nerve: The main function of neurons is to absorb sensory feedback from the internal and the external world through sensory nerves, send it to the Central nervous system (brain and spinal cord), and then transmit nerve impulses from the Central nervous system to the effectors (muscles and glands).
B) Nephron: The nephron is a functional and anatomical unit of the kidney that is part of the excretory system.
C) Glial: Glial cells (neuroglia) assist and nourish nerve cells, as well as kill pathogens and modulate impulse propagation.
D) Companion: Companion cells are a type of phloem cell that regulates the loading and unloading of sugars into sieve tube elements for translocation in flowering plants.

Therefore, the correct option is (A) Nerve as all information from our environment is detected by the specialized nerve cells.

Note: If the central nervous system is damaged then you may experience the sudden onset of one or more symptoms, such as tingling, numbness, or inability to move a part or all of one side of the body (paralysis). Double vision, dimness, loss of vision in both eyes or one eye, or blurring. Loss of speech, trouble in talking, or trouble in understanding speech.
