5. State the terms that are being defined. : A change over time in the responsiveness of the sensory system to a constant stimulus. Endorphins: Amino acid based hormones, that act as neurotransmitters that are released when the body is in pain or intense exercise to give a feeling of euphoria. Endorphin neuropeptides: Amino acid based chemicals with opiate and analgesic activity that occur naturally in the brain.

Change over time in the responsiveness of the sensory system to a constant stimulus. Endorphins: Amino acid-based hormones that act as neurotransmitters and are released when the body is in pain or during intense exercise to give a feeling of euphoria. Peptide Endorphins: Amino acid-based chemicals with opiate and analgesic activity that occur naturally in the brain.

Types of Receptors and Their Stimuli Match the receptor type with the environmental change that stimulates it. Type of stimulus Light energy Chemical concentrations Tissue damage Heat energy Pressure or movement Receptor type Photoreceptor Chemoreceptor Pain receptor Thermoreceptor Mechanoreceptor
During exercise, sensory receptors detect changes in oxygen and carbon dioxide levels in the blood. This information is then sent to the brain's medulla, which causes the heart to beat faster and increases the rate of breathing. Exercising also causes the nervous system to signal the pancreas and thyroid gland to release hormones which regulate metabolism.
