Animal Homeostasis (Endocrine System (Hypothalamus & Pituitary Gland…

- - - - main control of endocrine
        
        integrates and transmits nervous and endocrine systems
        
        link between nervous and endocrine system
      - communicates via pituitary gland
        
        other organs
        
        target cells
      - involved in regulating many BUT NOT ALL hormones
    - - releases hormones in response to hypothalamus signals
        
        communicate to cells and other endocrine organs
      - Split into two glands
        
        Posterior Pituitary
        
        extension of hypothalmus
        
        neurosecretory cells
        
        hormones (2) released in response to nervous system signalling
        
        signal detected
        
        nervous system signals sent to hypothalamus
        
        hormone release into bloodstream
        
        Oxytocin if the signal is nursing
        
        ADH if high salt levels in the blood
        
        Anterior Pituitary
        
        endocrine cell
        
        hormones
        
        ACTH
        
        adrenal glands
        
        TSH
        
        thyroid
        
        TRH -> TSH

        released via hypothalamus controls
        
        ANTERIOR CELLS ARE THE ONLY ONES CAPABLE OF RESPONDING TO HYPOTHALAMUS HORMONES
        
        hormones (multiple types)
        
        promote release of specific anterior pituitary hormone
        
        more hormone
        
        inhibiting hormone- release specific hormone
        
        less hormone
        
        hormones communicate messages to endocrine organ cells and other body cells
