Endocrine
A control system that acts by secreting hormones directly into the bloodstream, which then travel to other parts of the body to act on effectors (cells, tissues, organs)
G-protein coupled
Receptor type is important for oxytocin, GHRH, somatostatin, dopamine?
Tyrosine kinase
Receptor type is important for insulin, IGF-1?
Cytokine
Receptor type is important for EPO, leptin, prolactin and GH?
Steroid
Type of receptor is important for oestrogen
Homeostasis
The state of equilibrium of the body that is maintained by dynamic processes of feedback and regulation
Blood brain barrier
Important process for protecting neurones from blood
Prolactin
Acts on alveolar epithelial cells in the breast to induce synthesis and secretion of milk
Oxytocin
Acts on myoepithelial cells in the breast to induce contraction and ejection of the milk
Hypothalamus
Regulates and coordinates responses to changes in the external and internal environment
Posterior pituitary gland
Is made up of nerve terminals. Oxytocin and vasopressin are two important neurohormones released from
Anterior Pituitary Gland
Endocrine cells that secrete hormones into the general circulation
Somatotrophs
GH (growth hormone), stimulates growth
Lactotrophs
Prolactin - memory gland, lactation
Gonadotrophs
LH (luteinising hormone)
FSH (follicle stimulating hormone), both stimulate gonads
Thyrotrophs
TSH (thyroid stimulating hormone)
Corticotrophs
ACTH (adrenocorticotrophic hormone)
Dopamine
Releasing inhibitory factor for prolactin
Somatostatin
Releasing inhibitory factor for growth hormone (GH)
Growth hormone
- Major determinant of growth
- Increase number and size of cells in soft tissues
- Increase thickness and length of long bones
