Love letter to the Wattpad team: 💌
Plz stop flagging all the diagrams as 'inappropriate.'
Humans legit made ur app, so let us learn about that human body in peace ✨
plz & thx 😘
Love, fellow human beings with the same anatomy as you ♡

∴ The sympathetic nervous system is responsible for the 'fight or flight' response. This causes an increase in metabolic rate, heart rate, and BP; causes pupillary dilation The parasympathetic nervous system is responsible for the 'rest and digest' response. This causes a decrease in metabolic rate, heart rate & BP; constricts airways & causes pupil constriction.
ANS The ANS has a two motor neuron chain - Somatic nervous system has a one motor neuron - ANS has two motor neurons that synapse @ an autonomic ganglion in the PNS
🌸 Terminology 🌸 Preganglionic neurons - Cell bodies in the CNS - Axons are called preganglionic fibres Ganglionic Neurons - Cell boddies in on autonomic ganglia (becasue it starts in the ganglia) - Axons are called postganglionic fibres

🔴🔴BE ABLE TO DRAW THIS FOR BOTH TYPES 🔴🔴
Sympathetic Division - Preganglionic neurons short, post ganglionic are long - Cell bodies of preganglionic neurons are in the lateral horn of the spinal cord - thoracic and superior lumbar segments
