A short description about the human nervous system

2. THE NERVE TISSUE
IT IS FORMED BY CELLS CALLED NEURONS
PARTS OF NEURON
BODY OF THE CELL
AXON
DENDRITES
NEURONS ARE CONNECTED TO EACH OTHER BY MEANS OF THE DENDRITES
AND THE AXONS
TYPES OF NEURONS
SENSORY NEURONS
INTERNEURONS
MOTOR NEURONS
TRANSMISSION OF INFORMATION
THE NEURONS USE ELECTRICITY FOR TRANSMITTING INFORMATIONS WITH
NERVOUS IMPULSES.

3. HOW IS THE INFORMNATION CAPTURED?
THE SENSORY RECEPTORS CAPTURE EXTERNAL STIMULI (SUCH AS LIGHT, PRESSURE, HEAT...)
THE SENSORY NEURONS TAKE THE INFORMATION TO THE NERVOUS CENTRES.
THERE THE INFORMATION IS PROCESSED
THE SENSORIAL RECEPTORS ARE CONCENTRATED IN THE ORGANS OF THE FIVE SENSES
STIMULUS
SENSORY CELL PRODUCTION OF NERVOUS IMPULSES NEURON
NERVOUS CENTRE

4. TYPES OF RECEPTORS
TYPE LOCATION SENSATION TRANSMITTED
MECHANORECEPTORS
SKIN TOUCH AND PRESSURE
MUSCLES AND ARTICULATIONS POSITION AND MOVEMENT
VESTIBULUS OF THE EAR POSITION AND MOVEMENT
EAR CANAL HEARING
VISCERA DISTENSION
THERMORECEPTORS SKIN HEAT AND COLD
PHOTORECEPTORS RETINA OF THE EYE VISION
CHEMORECEPTORS OLFACTORY MUCUS SMELL
TASTE BUDS TASTE
NOCIRECEPTORS
SKIN SUPERFICIAL SOMATIC PAIN
MUSCLES AND ARTICULATIONS DEEP SOMATIC PAIN
VISCERA, VEINS, ARTERIES VISCERAL PAIN

5. WHAT IS THE NERVOUS SYSTEM LIKE?

6. THE ENCEPHALON

7. TYPES OF NERVOUS RESPONSES
REFLEX ARC THE RESPONSE IS ORDERED BY THE SPINAL CORD
VOLUNTARY ARC THE ENCEPHALON ORDERED THE RESPONSE
