The two systems that work together to cause this reaction are the endocrine system that secretes the hormone and the
Simora [160]

Two control systems of the body

Endocrine and Nervous

Endocrine and nervous system similarities

-Work together to maintain homeostasis

-Release ligands (chemical messengers) that bind to cellular receptors on particular target cells

Endocrine and nervous system differences

Endocrine system: -Transmits hormones through blood

-Targets any cell in the body with the correct receptor

-Very widespread

-Exhibits longer reaction times and has longer-lasting effects

Endocrine System

-Composed of ducts and glands that synthesize and secrete hormones

-Hormones are released into the blood and transported throughout the body

Endocrine system regulation growth and development

-Changes measured from birth to puberty

-Hormones help regulate embryonic cell division and differentiation

-Hormones regulate metabolism

How does the endocrine system maintain homeostasis or blood composition and volume

-Hypothalamus

-Hormones regulate blood solute concentrations (ex glucose ions)

-Hormones regulate blood volume, cellular concentration, and platelet numbers

The endocrine system controlling digestive processes

-Trigger digestion when food is in the stomach

-Hormones influence secretory processes and movement of materials in the digestive tract

Endocrine System controlling Reproductive Activities

-Make sure sperm and egg make it to each other

-Hormones affect the development and function of the reproductive system and the expression of sexual behavior

Endocrine Glands

Contain epithelial tissue that makes and releases hormones within a connective tissue framework

Endocrine Organs

-Glands with solely endocrine functions

-Ex: Pituitary, pineal, thyroid, parathyroid, and adrenal

Endocrine Cells

-Found in clusters in organs with another function

-Examples in Hypothalamus, Thymus, Heart, Stomach, Liver, Pancreas, Small Intestine, Adipose Connective Tissue

-Pancreases is not an endocrine gland, but it does release hormones

Which organelle serves as temporary storage of melanin or glycogen?
OLga [1]

Answer: Inclusions or inclusion structures serve as temporary storage of molecules like glycogen and melanin.

Inclusion structures are the aggregates formed of specific molecule types.

The inclusion bodies serve the purpose of temporary storage for molecules such as proteins, lipids, glycogen and melanin. One of the major differences between cell organelle and cell inclusion is that organelles are the living components or subcomponents which have particular functions but cell inclusions are non-living compounds or by products of metabolism process present in the cytoplasm.
