ENDOCRINE SYSTEM CONTROL
- PITUITARY AND HYPOTHALAMUS
- Pituitary is small gland situated in the STELLA TURCIA
- Just below the HYPOTHALAMUS
- It is connected to the hypothalamus via a STALK
- It is connected to the hypothalamus via a STALK
- Just below the HYPOTHALAMUS
- Pituitary is small gland situated in the STELLA TURCIA
- The Hypothalamus is a collection of SPECIALISED CELLS
- Located in the lower central part of the brain
- Is the primary link between the endocrine and nervous system
- Nerve cells here CONTROL THE PITUITARY
- either STIMULATE or SUPPRESS hormone secretion
- either STIMULATE or SUPPRESS hormone secretion
- Nerve cells here CONTROL THE PITUITARY
- Is the primary link between the endocrine and nervous system
- Located in the lower central part of the brain
- THE PITUITARY is the most important part of the endocrine system
- MASTER GLAND
- Secretions of hormones are influenced by emotions and seasons
- Secretions of hormones are influenced by emotions and seasons
- ANTERIOR AND PESTERIOR LOBES
- Posterior - NEUROHYPOPHYSIS composed of nervous tissue
- Anterior - ADENOHYPOPHYSIS composed of Glandular tissue
- Anterior - ADENOHYPOPHYSIS composed of Glandular tissue
- Posterior - NEUROHYPOPHYSIS composed of nervous tissue
- MASTER GLAND
- HYPOTHALAMUS AND POSTERIOR LOBE
- The posterior lobe connects to hypothalamus via NEURAL PATHWAYS
- Posterior lobe DOES NOT produce homrones
- Stores them and releases 2 peptide homones
- VASOPRESSIN AND OXYTOCIN
- Vasopressin - Anti diuretic hormone
- Oxytocin - contractions and release of milk
- Vasopressin - Anti diuretic hormone
- VASOPRESSIN AND OXYTOCIN
- Stores them and releases 2 peptide homones
- Posterior lobe DOES NOT produce homrones
- The posterior lobe connects to hypothalamus via NEURAL PATHWAYS
- HYPOTHALAMUS AND ANTERIOR LOBE
- Connects via unique VASCULAR LINK
- Synthesises hormones
- GH
- Thyroid Stimulating
- Adrenocorticotrophic - adrenal cortex to produce Cortisol
- Follicle Stimulating - sperm and ovarian follicles
- Lutenising - ovulation and sperm production
- Prolactin - breast growth and milk
- These hormones regulate body processes
- These hormones regulate body processes
- Prolactin - breast growth and milk
- Lutenising - ovulation and sperm production
- Follicle Stimulating - sperm and ovarian follicles
- Adrenocorticotrophic - adrenal cortex to produce Cortisol
- GH
- Synthesises hormones
- Connects via unique VASCULAR LINK
- HYPOTHALMIC HORMONES
- Hypothalamus controls the pituitary
- RELEASING and INHIBITING hormones
- control the release of hormones from Anterior LOBE
- control the release of hormones from Anterior LOBE
- RELEASING and INHIBITING hormones
- SOMATOSTATIN - inhibits growth hormone
- GROWTH STIMULATING HORMONE- releases GH
- GONADOTROPIN - Secretes LH and FSH
- THROTROPHIN - Secretes Thyroid Stimulating Hormone
- CORTICOTROPHIN - Secretes ACTH
- DOPAMINE - inhibits release of Prolactin
- CORTICOTROPHIN - Secretes ACTH
- THROTROPHIN - Secretes Thyroid Stimulating Hormone
- GONADOTROPIN - Secretes LH and FSH
- GROWTH STIMULATING HORMONE- releases GH
- Hypothalamus controls the pituitary
