Knowra Hypothalamus Hypothalamus The hypothalamus is a brain region that helps maintain internal stability by integrating neural and hormonal signals and regulating pituitary activity.
Hypothalamic–pituitary axis : A set of signaling pathways linking the hypothalamus and pituitary gland to regulate endocrine functions. It carries hypothalamic control into pituitary hormone secretion.
Diencephalon : The forebrain division that includes the thalamus, hypothalamus, epithalamus, and subthalamus. The hypothalamus is one of the diencephalon’s major subdivisions.
Thermoregulation : The physiological control of body temperature through heat production, conservation, and dissipation. Hypothalamic circuits compare thermal inputs with targets and coordinate temperature responses.
Walter Cannon : An American physiologist who developed the concept of homeostasis and studied bodily responses to emotion. His homeostasis framework captures a central function of hypothalamic regulation.
Pituitary gland : An endocrine gland beneath the brain that releases hormones regulating growth, reproduction, metabolism, and other functions. The pituitary executes many hormonal outputs that the hypothalamus directs.
Supraoptic nucleus : A hypothalamic nucleus whose neurons produce vasopressin and oxytocin for release from the posterior pituitary. Its neurons send hormones directly to the posterior pituitary.
Thalamus : A diencephalic structure that relays and processes much sensory and motor information en route to the cerebral cortex. It lies adjacent to the hypothalamus and shares the diencephalon with it.
Appetite : The motivational drive to seek and consume food, shaped by physiological and psychological signals. Hypothalamic networks integrate nutrient and hormone signals that influence eating.
Philip Bard : An American physiologist known for research on emotion and the neural organization of bodily responses. His work helped establish the hypothalamus’s role in emotional expression and autonomic response.
Autonomic nervous system : The nervous-system division that regulates involuntary functions such as heart rate, digestion, and pupil size. It provides rapid neural outputs that complement the hypothalamus’s slower endocrine control.
