Endocrine
Peptide or protein hormones require a second messenger to transmit their signal inside the cell. Upon binding to their receptor on the cell surface, these hormones activate intracellular signaling pathways that use second messengers like cAMP or Ca2+ to propagate the signal and elicit a cellular response.
A non-peptide hormone is a type of hormone that is not made up of amino acids arranged in a peptide chain. Instead, non-peptide hormones are typically small organic molecules or derivatives that act as signaling molecules in the body. Examples include steroid hormones like cortisol and sex hormones like estrogen and testosterone.
This could be one of two types of signaling:Paracrine signaling is where a signaling molecule produced from one cell affects other types of adjacent cells.Autocrine signaling is where a signaling molecule produced from one cell affects itself and other adjacent cells of the same type.
No, proteins are not steroid hormones. Steroid hormones are a type of hormone derived from cholesterol, while proteins are large molecules made up of amino acids. Steroid hormones are lipid-soluble and are involved in regulating various physiological functions, while proteins have diverse functions in the body such as providing structure, facilitating chemical reactions, and signaling.
Steroids are a type of lipid that have a ring structure. Hormones like cholesterol and sex hormones are examples of steroids.

Paracrine means it is does not involve the bloodstream. It does however involve cellular secretion of signaling molecules to local cells. Synaptic signaling is a paracrine type signaling but rather than being secreted to several local cells in the vicinity of the signaling cell, the signaling molecules are just secreted to a receptor cell only a narrow space away. Imagine working in an office of cubicals. Toss wadded up notes up over your wall and into the 10 closest cubicals and compare that too just tossing it to the one next to you.

it binds with several signaling molecules as it has shape that is complementary to signaling molecules.
Paracrine signaling is a form of cell signaling in which the target cell is near ("para" = near) the signal-releasing cell.A distinction is sometimes made between paracrine and autocrine signaling. Both affect neighboring cells, but whereas autocrine signaling occurs among the same types of cells, paracrine signaling affects other types of (adjacent) cells.

No, steroid hormones are not proteins. They are a type of lipid molecule that are derived from cholesterol.
