*Peripheral Nervous System and Endocrine System

Flashcards covering key concepts related to the peripheral nervous system and the endocrine system, including their functions and relationships.

Peripheral Nervous System

Coordinates with the brain to ensure proper body function.

Somatic Nervous System

Part of the peripheral nervous system responsible for voluntary control of body movements.

Automatic Nervous System

Part of the peripheral nervous system that controls involuntary bodily functions.

Sympathetic Nervous System

Mobilizes the body during stress or danger, rapidly activating organs and glands.

Parasympathetic Nervous System

Balances the sympathetic nervous system and normalizes arousal after stress.

Endocrine System

System of glands producing hormones released into the bloodstream, closely linked to the immune system.

Adrenal Gland

Produces epinephrine/adrenaline, involved in stress response.

Thyroid

Produces thyroxine, which regulates metabolism and energy.

Pituitary Gland

Produces regulatory hormones that control several body functions.

Gonadal Glands

Produce sex hormones like testosterone and estrogen.

Hypothalamic-pituitary-adrenal (HPA) Axis

A major neuroendocrine system that controls stress reactions and regulates body processes like digestion and mood.

Corticotropin Hormone (CRH)

Released by the hypothalamus and stimulates the production of cortisol.

Cortisol

A hormone produced by the adrenal glands, involved in stress response.
