Q. I. The endocrine system provides chemical integration through hormones II. The neural system provides an oragnised network of point to point connection for a quick coordination III. The neural organization is very complex in lower invertebrates IV. The human neural system includes CNS and PNS Select the correct statements
A) Only I
B) I and II
C) I, II and IV
D) I, II and III
Explanation
The human neural system includes CNS and PNS. Nervous system exercise control by sending electrical signals called nerve impulses. The endocrine system consists of specialized glands, which bring about control by sending chemical messengers termed as hormones. For a quick coordination, it is neural system that provides an organised network of point to point connections. In lower invertebrates, the neural organization is very simple
