How do we stimulate the release of a chemical signal ?

Neurosecretion

Hormones are synthesized + released from a neuron

Anti-divertic Hormones (Neurosecretion)

Produced/ released by the hypothalamus

Release Factors (Neurosecretion)

Will be secreted to regulate the release of other hormones

Classical Endocrine Secretion

The synthesis and release of hormones will be in a glandular cell in response to a change in the concentration of ECF

ECF

extracellular fluid (outside the cell)

Thyroid Hormones

is released in response to increace in the cone of TST in the blood

TST

testosterone

Aldosterone

Synthesis + release of aid. It is regulated by an increase in K levels in the blood.

Innovated Endocrine cell structure

A signal from the nervous system will direct an endocrine cell to synthesize and release the hormones

Example of an innovative endocrine cell structure

Epinephrine = "Fight-or-Flight"
