Nervous system
- Central Nervous system
- Encephalon:
upper part
- Brain
- Cerebellum:
cordination
&body
movement
- Thalamus: picks
up sensorial
info and sends
it to cerebral
cortex
- Hypothalamus: Regulates the
medium hemostasis functions
- Cerebral cortex
- SUPERIOR FUNCTIONS: Conscious
perception, Reasoning & memory,
- SENSORIAL PERCEPTION:
Somatosensorial, Audition, Vission
- MOTOR CORTEX:
Voluntary
movements
- Brainstem: controls
essential functions
- Spinal cord
- Runs along dorsal
part of the body
- Receives and transports the
ascendant and descendant
information.
- Receives all sensorial information
that is given from all parts of the
body; works as a highway
- Controls two different types of
movements, simple and fast movements
which are called as defense reflex
- Peripheral nervous system
- Connects the Central Nervous System with the limbs and organs
- Sensory: Afferent neurons that relay nerve
impulses TOWARDS the central nervous
system.
- Autonomic: regulates
involuntary actions
- Sympathetic
- Dominates in stressful or emergency
situations
- Makes heart beat faster
- Parasympathetic
- Relaxes the organism
- Controls respiration,
heartbeat and other vital
functions
- Somatic: governs
voluntary actions and the
body reflexes
- Motor: Efferent neurons that relay
nerve impulses AWAY from the
central nervous system.
