(ii) It released into the blood and transported to a distantly located target organ.
(iii) Large number of chemicals act as hormones and provide coordination in the vertebrates.
(iv) Invertebrates possess very simple endocrine systems with few hormones.
(v) Hormones may be peptide, polypeptide, protein, steroids and amino acid derivatives.
(vi) Glucagon, cortisol, epinephrine and thyroid hormones are proteinaceous hormone.
(vii) Hormones are also secreted by some tissues which are not endocrine glands.

Given is the diagrammatic representation of impulse conduction through an axon (at points $A$ and $B$). View the diagram and arrange the steps of impulse conduction

$I.$ The polarity of the membrane at site $A$ is reversed and depolarized, i.e., the outer surface becomes negatively charged and the innerside becomes positively charged, generating nerve impulse

$II$. A stimulus causes disturbance to the membrane at site of $A$ nerve fibre resulting in leakage of $N a^{+i i}$ ions inside the nerve fibre

$III.$ On the outer surface, current flows from site $B$ to site $A$ to complete the circuit of current flow. Hence, the polarity at the site is reversed, and an action potential is generated at site $B.$ The impulse (action potential) generated at site $A$ arrives at site $B .$ The sequence is repeated along the length of the axon and consequently the impulse is conducted

$IV.$ Immediately ahead, the axon $(e \cdot g .$, site $B )$ membrane has a positive charge on the outer surface and a negative charge on its inner surface. As a result, a current flows on the inner surface from site $A$ to site $B$
