Notes

CNS

● Brain: voluntary + involuntary responses
● Spinal cord: reflex actions

Group of neurons: nuclei

Group of axons: tracts

PNS (neurons outside CNS)

● Somatic division: voluntary movement through effectors

Axons connect cell body in CNS to skeletal muscle via neurone outside CNS

● Autonomic : involuntary responses with effectors

Preganglionic neurone in CNS connects to autonomic ganglion that’s connected to
effector by postganglionic neuron

- Sympathetic ns: fight or flight
- Parasympathetic: rest + digest

Groups of neurons: ganglia

Groups of axons: nerves


BRAIN

● Cerebrum: most of mass, controls thoughts + actions. Split into 2 hemispheres
connected by corpus callosum

, ● Frontal lobe: emotions, reasoning, problem solving + planning
● Temporal: sensory processing of hearing, memory formation, language, facial
recognition
● Occipital: visual processing
● Parietal: integrates sensory info
● Cerebellum: coordinates balance, movement + body posture (fine motor control)
● Medulla oblongata: regulate breathing, swallowing, circulation, digestion + sneezing
reflex. Connects spinal cord to higher regions
● Hypothalamus: thermoregulation, hunger, control pituitary gland, secretes ADH


Sympathetic Nervous System

fight or flight response.

➢ Preganglionic nerves release Ach at synapses
➢ Norepinephrine: btw postganglionic nerves + effectors

Binds with adrenergic receptors in blood vessels, heart, eye muscles, exocrine
glands

➢ Ach stimulates sweat glands

Inhibits peripheral vision to focus sight on potential danger

Parasympathetic System

rest and digest

➢ Pre + postganglionic neurones release Ach at synapses
➢ Ach binds with muscarinic receptors in eye muscles, bronchioles, heart, smooth
muscle in digestive tract



Sympathetic Parasympathetic

Heart rate Increased decreased

Blood vessels Vasoconstriction Vasodilation
