The Power and Control of the Nervous System

• The nervous system is divided into two main parts, the central nervous system (CNS) consisting of the brain and spinal cord, and the peripheral nervous system (PNS), which includes all other nerves.
• The brain has three main parts: the cerebrum, cerebellum and brainstem.
• there are 3 main division of the brain: forebrain, midbrain and hindbrain.
• nerve: hand and reproductive system, parts: feet
• the nervous system consist of the brain, spinal cord and all of the nerve.
• nervous system is the major control system of homeostasis and the "main processing center"
• it provides monitoring, response, and regulation of all system in the human body and other organisms.
• the nervous system is divided into two the central nervous system and the peripheral nervous system.
• the central nervous system is made up of the brain and spinal cord.
• the central nervous system and the peripheral nervous system work together to make rapid change in your body in response to stimuli.
• the peripheral nervous system has two subdivisions the somatic nervous system and the autonomic nervous system.
• the somatic nervous system focuses on the voluntary activities.
• the autonomic nervous system focuses on the in voluntary avtivities.
• the autonomic nervous system has two subdivision the sympathetic nervous system and parasympathetic nervous system.
• the sympathetic nervous system are in control in times of stress.
• the parasympathetic nervous system controls the body in times of relaxed.
• The cranial nerves are a set of 12 paired nerves in the back of your brain.
• Cervical nerves C1, C2 and C3 control your forward, backward and side head and neck movements.
• The thoracic nerves refer to the cluster of nerve fibers found in the upper body, particularly within the chest region.
• Nerves of the lumbar spine you have five pairs of lumbar spinal nerves, one that branches off from the right and left sides of L1 to L5.
• The sacral plexus is a network of nerve fibres that supplies the skin and muscles of the pelvis and lower limb.
• cerebrum the larger part of the brain.
• cerebellum is located at the back and at the bottom of the brain.
• brain stem is the smaller parts of the brain.
• the cerebrum controls conscious activities, memory, language, and intelligence.
• the cerebrum are covers with an outer layer of fat called grey matter and an inner layer of white matter.
• the cerebrum are divided into a 4 lobes temporal lobe - memory, emotion, hearing, and language, frontal lobe - planning, judgment, and decision making, parietal lobe - touch, taste, and smell, parietal lobe processing of sensory information and occipital lobe - vision
• the cerebellum is the muscle coordination is developed here as well as the memory of physical skills.
• brain stem has 3 parts: medulla oblongata, pons, and midbrain.
• brain stem in voluntary activities.
• the neuron is another name for the nerve cell, it is the basic unit of the nervous system.
• the most important parts of the neuron or nerve cell are dendrites and the axon.
• the neuron has parts it is the cell body, dendrites, axon, action potential, myelin sheath, terminal buttons and dendrites (from another neuron).
• the neuron have 3 main function it is the sensory neuron, relay neuron and motor neuron.
