No, tropic hormones are not always classified as neurohormones. Tropic hormones are a type of hormone that regulate the secretion of other hormones, while neurohormones are produced by neurons and released into the bloodstream. Some tropic hormones may be neurohormones, but not all tropic hormones fall into this category.
Yes, the pineal gland is classified as an endocrine gland because it secretes hormones directly into the bloodstream.
This gland would be classified as an exocrine gland. Exocrine glands secrete their products, such as enzymes or hormones, through ducts directly to the external environment or surface of the body.
"Glands without ducts" are called "ductless" or "endocrine" glands. These include the pancreas and pituitary gland. Endocrine glands produce hormones, which are then carried by the bloodstream for transport around the body. The opposite type of gland is called the exocrine glands. They include the sweat gland and the salivary gland: they have ducts, which pass hormones or other substances directly to where they are needed.
Mammary gland consist of glandular tissue and fatty tissue in them. Mammary glands are characteristic of mammals.

Some tropic hormones may be neurohormones, but not all tropic hormones fall into this category.
Epinephrine and norepinephrine are the two hormones secreted by the adrenal medulla. These adrenal hormones are classified as catecholamine's which are chemical compounds made in the body from the amino acid tyrosine.
Some hormones (such as steroids) are classified under lipids which actually belong to Esters group. Other hormones are proteins which belong to amine group (they are made up of amino acids).
Hormones are primarily classified into two main categories: steroid hormones and peptide (or protein) hormones. Steroid hormones, such as cortisol and estrogen, are derived from cholesterol and are lipid-soluble, allowing them to pass through cell membranes. Peptide hormones, like insulin and growth hormone, are composed of amino acids and are typically water-soluble, requiring receptors on the cell surface to exert their effects.
Steroids are a class of lipid molecules that have 4 carbon rings.
Yes, the pineal gland is classified as an endocrine gland because it secretes hormones directly into the bloodstream.
Yes, hormones are classified into two main categories: steroid hormones and non-steroid hormones. Steroid hormones, such as cortisol and estrogen, are derived from cholesterol and can easily pass through cell membranes to interact with intracellular receptors. Non-steroid hormones, which include peptide and amino acid-derived hormones like insulin and adrenaline, are generally unable to cross cell membranes and typically exert their effects by binding to receptors on the cell surface. This classification reflects their chemical structure and mechanism of action in the body.

The endocrine system secretes hormones directly into the bloodstream. These hormones usually have target organs that they control. Hope this helps A RN in NJ
