Thermoregulation, Charlie Mitchell - Coggle Diagram

- - - - Controls pituitary gland
        
        Stimulates other glands (such as thyroid)
        
        Releases hormones such as (growth hormone (GH), prolactin (PRL), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) in its anterior lobe, and produces oxytocin and antidiuretic hormone (ADH) (also called vasopressin) in its posterior lobe)
        
        endocrine gland located at the base of the brain, it controls body functions (growth, metabolism, and reproduction)
      - regulating essential functions such as temperature, hunger, sleep, growth, and reproduction
        
        it reacts to core temp changes and nerve impulses from receptors in the skin.
      - body's command center
      - Vasodilation
        smooth muscle in blood vessel walls relaxes, causing the vessels to widen and increase blood flow
        
        increased skin blood flow to dissipate heat
  - - - TRP (Transient Receptor Potential) family
        
        COLD RECEPTORS
        TRPM8 and TRPA1
        
        HOT RECEPTORS
        (TRPV1) channel for noxious heat, and TRPV3, TRPV4, and TRPM2 for physiological warmth
    - - Wind chill
      - External cold temperatures
      - Improper clothing
      - Being wet
        (water has a higher heat conductivity in contrast to air thus body temp will reduce if covered in water)
      - Dehydration
        (lower blood volume reduces heat capacity)
  - - - Adrenaline
        increases the metabolic rate by promoting the breakdown of glycogen to glucose and raising heart rate and blood flow
      - Thyroxine
        Higher thyroxine levels stimulate cells to consume more oxygen and nutrients, boosting metabolic activity across the body, which in turn increases heat production.
  - - - ATP is used as fuel. As muscles convert ATP to energy, much of it is released as heat
        
        Raised body temperature as result
  - - - sweat evaporates from skin and heat is absorbed from body
