ESS 302 - Hormones I

Front

What are steroid hormones?

Back

Steroid hormones are lipid-soluble hormones derived from cholesterol that regulate various physiological processes.

Front

What is the function of paracrine signaling?

Back

Paracrine signaling functions by the release of signaling molecules that affect nearby cells.

Front

What do gap junctions allow?

Back

Gap junctions allow direct communication between adjacent cells.

Front

What regions does the endocrine system impact?

Back

The endocrine system impacts many regions of the body.

Front

How are peptide hormones defined?

Back

Peptide hormones are short chains of amino acids that function as signaling molecules.

Front

What is the primary characteristic of lipid-soluble hormones?

Back

Lipid-soluble hormones can easily pass through cell membranes due to their hydrophobic nature.

Front

What role do signaling molecules play in cellular communication?

Back

Signaling molecules facilitate communication between cells, influencing their behavior and function.

Front

How do endocrine hormones differ from paracrine signals?

Back

Endocrine hormones are released into the bloodstream and affect distant target cells, while paracrine signals affect nearby cells.

Front

What is the significance of direct cell communication via gap junctions?

Back

Direct communication via gap junctions allows for rapid and coordinated responses between adjacent cells.

Front

What are the two main types of hormones in the endocrine system?

Back

The two main types of hormones are steroid hormones and peptide hormones.
