1. Important parts
1.1. Sensory input
1.1.1. Are the sensories that dectec in one part of your body
1.2. Integration
1.2.1. The process and decides what you should be done about it
1.3. Motor Output
1.3.1. Activates certain parts of our body
2. Organization
2.1. Central Nervous system
2.1.1. it compose from the brain and the spinal cord
2.1.2. It´s the main control center
2.2. Periferal nervous system
2.2.1. Allow to the central nervous system to comunicate whith the rest of you body
2.2.2. It compose of all the nerves that are conected whith the brain and spinal cord
2.2.3. Parts of the periferal nervous system
2.2.3.1. Sensory division (afferent)
2.2.3.1.1. Picks up sensory stimulls
2.2.3.2. Motor Division (efferent)
2.2.3.2.1. Sends directin from the brain to the muscles and glands
2.2.3.2.2. Somatic Nervous System (voluntary)
2.2.3.2.3. Autonomic Nervous System (involuntary)
3. Is made of nervous tissue
3.1. Its made of cells and this cells are cold neuron cells
3.1.1. respond the stimuli
3.1.2. Transmit señals
3.1.3. They are sorounded and protected by folks of glia cells
3.1.4. In the centarl nervous system
3.1.4.1. Astrosytes
3.1.4.1.1. Exchange the materials between neurons and capillares
3.1.4.2. Microglial cells
3.1.4.2.1. Inmune defense against invading microorganisms in the brain and spinal cord
3.1.4.3. Ependymal cells
3.1.4.3.1. Create, secrete and circulate cerebrospinal fluid
3.1.4.4. Obligodendrosytes
3.1.4.4.1. Produce an insulating barrier calling the mylin sheath
3.1.5. Periferal nervous system
3.1.5.1. Satelite cells
3.1.5.1.1. Surround and suport neuron cell bodies
3.1.5.2. Schawann cells
3.1.5.2.1. Produce an insulating barrier calling the mylin sheath
3.2. Neurons
3.2.1. Are some of the largest-lived cells in the body
3.2.2. Neurons are irreplaceables
3.2.3. Need a lot of glucose and oxygen
3.2.4. Neurons parts
3.2.4.1. Cell body
3.2.4.2. Denrites
3.2.4.3. Axon
3.2.4.3.1. Transmit electrical impulses away from the cell body to the other cells
3.2.5. Function
3.2.5.1. Sensory Nurons (afferent neurons)
3.2.5.1.1. Transmit impulses from sensory reseptors toward the CNS
3.2.5.1.2. More of this are Unipolar
3.2.5.2. Motor Neurons (efferent neurons)
3.2.5.2.1. Impulse moves from the CNS to the rest of the body
3.2.5.2.2. Mostly multipolar
3.2.5.3. Inteneurons (association neurons)
3.2.5.3.1. Impulse moves between sensory and motor neurons
3.2.5.3.2. Mostly multipolar
