Nervous System Notes
- Central Nervous System- receives information from your body to help you react to the stimuli.
- Cerebral Hemisphere- the cerebral hemisphere controls conscious thought, memory, controls voluntary movements, learning, reasoning, and behavior.
- Brainstem- the brainstem connects the spinal cord with the cerebrum and it processes all sensory and motor functions.
- Epithalamus- some functions of its components include the secretion of melatonin, it controls circadian rhythms, regulation of motor patterns, and emotion.
- Thalamus- the thalamus receives signals modulates the flow of information and sends them to the cortex.
- Hypothalamus-it receives the taste and smell information
- Midbrain- the midbrain is part of the central nervous system and controls vision, hearing and the control of motor movements, consciousness, and temperature.
- Pons- in the brain the pons relays sensory information between the cerebellum and the cerebrum it relays information and controls arousal. It relays information from the two parts of your brain.
- Midulla-the medulla oblongata is the part of the brain that controls breathing, heart rate and blood pressure in your body.
- Cerebellum-the cerebellum modulates rather than and initiates movement it controls motor skills like balance and coordination.
- Spinal Cord-the spinal cord carries impulses between your body and your brain.
- Peripheral Nervous System-the peripheral nervous system carries information from the organs muscles and glands to your brain.
- Cranial Nerves- cranial nerves are nerves directly connected to the brain they controlled the eyes mouth and ears in the muscles on your face.
- Spinal Nerves- spinal nerves transmit signals between the brain and the rest of the body which are interpreted as pain, touch, pressure, sensation, or temperature.
- Receptor-receptors sense what is going on in your body and relays the information back to your brain.
- Sensory Neuron- sensory neurons converts various external stimuli that come from the environment into corresponding internal stimuli and convey sensory information to the brain.
- Posterior Root- the posterior root is a nerve fiber bundle of spinal nerves that carry sensory information to the central nervous system.
- Ganglion-is regarded as the gray matter of the spinal cord.
- Motor Neuron-the motor neuron is a nerve cell that specifically controls the voluntary muscles of your body.
- Anterior Root- the anterior root is also called the ventral root it carries neural signals away from the central nervous system towards the limbs and the organs.
- Effector- the effector is the gland or the muscle that causes the response stimulated by the nervous system.
