Hypothalamous

  • Regulats the sympathetic branch of the ANS

  • Controls the pituitary gland (belongs to the endocrine system)
1 of 7

PNS

  • PERIPHERAL NERVOUS SYSTEM
  • sends information to the CNS from the outside world
  • sends info from CNS to produce particular behaviours (via muscles)

ANS

  • AUTONOMIC NERVOUS SYSTEM
  • regulates internal bodily functions without concious thought (i.e. breathing)
  • Linked to the viscera which are involuntary (i.e. heart)

Sympathetic Branch

  • Prepares body for activity/energy expenditure
  • Stimulates physological changes which help us defend ourselves (e.g. heart rate increases)

Parasympathetic Branch

  • Brings the body back down (parachute)
  • Stimulates processes to restore/conserve energy
  • Predominates when we're relaxed/inactive or following an emergency (e.g. heart rate decreases)

Endocrine (Hormonal) System)

  • Hormones are released directly into the bloodstream and are carried through the body.
  • The pituitary gland: releases hormones which control the secretion of hormones from other glands
  • Adrenal glands: very important. Each comprise of an inner core (adrena medulla) and an outer layer (adrenal cortex)
