23 Year old male with severe face and arm muscle spasms
Downstream;
Left untreated
laryngeal spasm can lead to asphyxiation.
Bloodstream
Autonomic dysfunction can cause cardiac arrhythmias and fluctuations in blood pressure
violent muscular spasms
Ca not releasing

Physiology
Systems
Respiratory
Lungs, bronchi, diaphragm
Supplies bloods with oxygen, Removes co2, acid base balance
Integumentary
Skin
1st line of defense,Protects organs from injury
Muscular
Skeletal muscle including diagram
Allows for movement, Produces heat
Nervous
Brain, Spinal cord, Nerves
Fast acting control system responds to internal/external changes
Skeletal
Skeletal bones
Framework for muscle movement, site of hematapoesis, stores minerals
Circulatory
Heart and blood vessles
Transports blood carrying Oxygen, Co2, nutrients, and waste
Neuromuscular Junction
Axon terminals
Part of neurons that contain synaptic vessicles
Synaptic vessicles
Contain Acetylcholine
Neurotransmitter Acetylcholine (Ach)
Will exocytose by action potential in the neuron, into synaptic cleft, then motor end plate
Synaptic cleft has acetylcholinesterase
Ligand gated channels
Ach attaches to receptors on sarcolemma opening channels
Sodium
Sodium rushes into muscle fiber, causes resting membrane potential (-70mV) to depolarize (more positive)
Voltage gated
Channels open, domino effect, due to sodium flooding, down t-tubles in muscle fiber
Sarcoplasmic reticulum
2 more items...
Exocytosis
Vesicles go to cell membrane
Vesicles attach to cell membrane
Cell membrane releases vesicle contents
Frequency
Twitch
Isolsated muscle contraction
Wave summation
increase in contractile strength, no relaxation
tetney
Stays contracted
Clostridium tetani
Tetnus
Toxin: Tetanospasmin
produces violent spasms , found in soil, can get in through skin by use of dirty needles
Prevents Ca release
Patient never vaccinated against this bacterium
