Study Notes
Para-crine Communication
- Para-crine communication involves substances that reach nearby cells, facilitating local signaling.
- This mechanism is crucial in various physiological processes, influencing cell behaviors within a tissue.
The Nerve
- Nerve communication occurs through neurotransmitters, which transmit signals from one cell to another, enabling rapid communication within the nervous system.
Prefix and Suffix
- Hypo- indicates a decrease; example: Hypo-tension (low blood pressure).
- Hyper- signifies three; example: Triceps (muscle with three heads).
- Supra- means above; example: Suprarenal gland (gland located above the kidney).
- Infra- indicates below; example: Infrared waves (electromagnetic radiation below the visible spectrum).
- Poly- denotes many; typically used in terms like "polyunsaturated."
Ribosomes
- Ribosomes consist of two subunits: a small subunit and a large subunit.
- These structures are essential for protein synthesis, translating messenger RNA into amino acid chains.
