HypothalamusClark Mannas andHarrison Cardwell4B

The hypothalamus is located in the brain

It is central, under the thalamus Some of the main functions

involve body temperature control and the linking of the nervous system to the endocrine system with the pituitary gland.

The hypothalamus has many distinct nuclei

It is highly connected with other parts of the brain and nervous system

Overview

Gonadotropin (releasing hormone – GnRH) Controls follicle stimulating hormone (FSH) and luteinizing hormone (LH), stimulates testes and ovaries

Thyrotropin (releasing hormone – TRH) Promotes thryoid stimulating hormone (TSH) and prolactin (PRL) secretion

Corticotropin (releasing hormone – CRH) Promotes growth hormone (GH) secretion

Somatostatin Inhibits GH and TSH secretion Antidiuretic Hormone (ADH) Prevents dehydration

through reduced urine volume and subsequent greater water retention

Oxytocin (OT) Responsible for feelings of lust and love, is especially prevalent in sexual intercourse

Hormone Production

Regulation

The Hypothalamic-Pituitary Axis is unique in its self-regulation; the hormones of one (for instance, cortisol, an inhibitor for the hypothalamus) will bind to the other, stoppping further production

This perfect, symbiotic relationship is referred to as negative feedback inhibition

Hypothalamic disease

Hypothalamic disease can be caused by eating disorders or malnutrition, as well as genetic disorders or trauma

This can interfere with hormone production as well as the maintenance of homeostasis

The vast area of effect yields symptoms ranging from vision loss to tumors to impotence

As far as treatment, the tumors can be dealt with through surgery or radiation, where the hormone deficiencies can be handled with a replacement of those that are lacking
