Homeostasis/Control Mechanisms
Human Cells
Purpose of organelles
Ribosomes help with protein production
Mitochondria powers cells with ATP
Golgi bodies package proteins and lips for transport
Rough endoplasmic reticulum synthesises and folds proteins, whilst the SER is involved in lipid synthesis, detoxification and calcium storage.
Neural/Endocrince Control
Neural (Faster response)
PNS (Peripheral Nervous System)
Motor Division
Autonomic (Involuntary)
Reflexes?
Somatic (Voluntary)
Cortico-spinal Tract (Direct path from cerebral cortex to spinal cord)
Indirect Pathways (Vestibulo and reticule spinal tracts)
Blance and movements (Cerebellum)
Sensory Division
CNS (Central Nervous System)
Brain/Spinal Cord
Reflexes
Illness
Disorders
Affects more aspects of health
Syndromes
A group of signs/symptoms present together
Disease
Abnormality that causes anatonomical/physiological changes
Causes
Non-communicable
Congenital
Communicable
Acquired
Terms
Life limiting - Restrictive chnages that impacts lifespan
Acute on Chronic - "Flare up" event
Progressive - will become worse
Sub Acute - Can't be classified as acute but closer to chronic
Chronic changes - requires long term management
Acute alteration - responds to rapid treatment
Positive feedback loops
Examples are blood clotting or birth contractions
Stimulus is intensified until problem is solved
Negative feedback loops (3 Components)
Effector - responds to reverse the stimulus (Neural/endocrine)
Control Centre - The Brain compares the receptors stimulus with the normal and creates an action
Sensor (referred to a receptor) - monitors a specific physiological response
ATP Metabolism
Energy is created when the ATP Spilit. One of the triphosphghates spilt and create energy
Muslces recycle released ATP
Illnesses disrupt the recycling procedure, patients tire faster due to this
Glucose + Oxygen will create 30/32 ATP to fuel the cell. CO2 and H2O are waste products
Creatine helps recycle phophates
Function of cell membrane
Steroids pass through and act on nucleus
Has a Phospholipid bi-layer
Semi-permeable (Allows certain molecules through)
