Nervous system
CNS
PNS
Clump of neurons
○
Responsible for complex behaviours, thought, perception, emotion
○
2 hemispheres - right and left)
○
Ventricles - cavities filled with cerebro-spinal fluid, sewerage system of
CNS
○
Screen clipping taken: 4/11/2017 12:20 PM
Brain stem - base of brain, swollen head on top of spinal cord,
controls life supporting functions
○
Cerebellum (small brain on brainstem) - control of precision
movements
○
Thalamus and hypothalamus - thalamus = sensory relay to cortex,
hypo = hormonal regulation and motivational control (feeding and
sex)
○
Main subdivisons
Limbic system - wraps around thalamus, involved in control of
emotion and memory
○
Screen clipping taken: 4/11/2017 12:25 PM
Basal ganglia - wraps around thalamus, invovled in action and
thought
○
Brain
-
Sensory nerves -> input to CNS from
sensory organs
-
Motor nerves -> output from CNS to
muscles
-
Controls many non-voluntary
bodily functions e.g. digestion,
heart rate, blood pressure,
sweating, pupil size, genitals
(4Fs - food….fucking)
•
Sympathetic - prepares
for action
○
Parasympathetic -
involved in rest and
recuperation
○
2 branches
•
Uses same neurotransmitters
as brain (Ach and NA)
•
Some drugs used to treat
psychological/neurological
conditions in brain can affect
function of ANS
•
Autonomic nervous system
-
Half a billion neurons in gut
•
Interacts with brain via
sympathetic and
parasympathetic NS but can
also function independently
(2nd brain)
•
Controls digestive activity
(peristalsis and secretion of
enzymes) and sense physical
and chemical conditions of gut
•
Uses same neurotransmitters
as in brain incl. dopamine and
serotonin
•
Enteric nervous system

Document Summary
L1 and 2- divisions of the nervous system, anatomy, physiology, comparative neuroanatomy. Ventricles - cavities filled with cerebro-spinal fluid, sewerage system of. Brain stem - base of brain, swollen head on top of spinal cord, controls life supporting functions. Cerebellum (small brain on brainstem) - control of precision movements. Thalamus and hypothalamus - thalamus = sensory relay to cortex, hypo = hormonal regulation and motivational control (feeding and sex) Sensory nerves -> input to cns from sensory organs. Motor nerves -> output from cns to muscles. Controls many non-voluntary bodily functions e. g. digestion, heart rate, blood pressure, sweating, pupil size, genitals (4fs - food . fucking) Uses same neurotransmitters as brain (ach and na) Some drugs used to treat psychological/neurological conditions in brain can affect function of ans. Interacts with brain via sympathetic and parasympathetic ns but can also function independently (2nd brain) Controls digestive activity (peristalsis and secretion of enzymes) and sense physical and chemical conditions of gut.
