Question

Intercellular communication in multicellular organisms occur through

• A. Digestive system
• B. Nervous system
• C. Both-nervous and endocrine systems
• D. Respiratory system only

Answer 1

The correct option is C Both-nervous and endocrine systems

In most higher animals there are two major pathways, or systems, of intercellular communication, the endocrine system and the nervous system. In the endocrine system, specialized glandular cells secrete hormones, which are carried in the bloodstream to target cells. In the nervous system, sensory receptor cells and a network of nerve cells with elongated processes communicate with one another and with muscles and glands by secreting neurotransmitters directly onto specific receiving cell.

So, option C is the correct option.
