NERVOUS SYSTEM - Coggle Diagram
NERVOUS SYSTEM
The Sense
Eye
(Vision)
=Eyebrow
(Prevents sweat from trickling into the eyes)
=Eyelid
(Covers and protect the eyes)
-Reflexive blinking every few second
-Secretions keep eyes moist
=Eyelashes
(Trigger reflex blinking)
Nose
(smelling)
=Chemoreceptors
-Volatile substances (easliy evaporated)
=Olfactory neurons
=Olfactory receptor
Ears
(Hearing)
Middle ear
Inner ear
External ear
=Helix
=Auditory canal
=Auricle
=Lobule
Tongue
=Allows for perception of taste
Taste buds
=Gustatory epithelial cells
=Chemoreceptors basal epithelial cells
=Stem cell that replace gustatory epithelial cell as they get damaged or burnt
Most foods combine these in a unique way
=Sour
=Sweet
=Bitter
=Umami
=Salty
Touch
=Vibration
=Temperature
=Pain
Types Of Nerves
2.Sensory Nerves
=Transmit impulse to the Central Nervous System
=Contains sensory neuron
3.Motor Nerves
=Contain motor neurons
=Transmit impulses from the Central Nervous System
1.Mixed Nerves
=Contain both sensory and motor neurons
=Transmit impulse to and from the Central Nervous System
CRANIAL NERVES
Abducens
Facial
Trigeminal
Vestibulocochlear
Trochlear
Hypoglossal
Oculomotor
Glossopharnylgeal
Optic
Accessory
Olfactory
Vagus
CENTRAL NERVOUS SYSTEM
=Brain
=Spinal Cord
PERIPHERAL NERVOUS SYSTEM
Sensory/Apperent Division
Include the somatosensory system (receptors)
=The receptors send a signal to the brain
=Perception (pain)
=The signal is interpreted and assesed
=Entry point for any stimulus
Type of Sensory Receptors
2.Location on the body
=Exteroceptors
(Respond to stimuli outside of the body)
=Interoceptors
(Respond to stimuli inside the body)
=Proprioceptors
(Respond to stimuli in skeletal muscle and related connective tissue)
1.Type of Stimulus
=Photoreceptors
(Respond to light)
=Chemoreceptors
(Respond to specific chemical )
=Nociceptors
(Respond to damaging stimuli
=Themoreceptors
(Respond to temperature change )
=Mechanoreceptors
(respond to touch/pressure)
3.Structure
=Bulbous corpuscles
=Muscle spindles
=Lamellar corpuscles
=Tendon organs
=Encapsulated nerve endings
=Joint kinesthetic receptors
=Nonencapsulated nerve endings
Motor/Efferent Division
=Response
