The central nervous system is the complex of nerve tissues that control the activities of the body. It consists of the brain and the spinal cord.
The peripheral nervous system is the nervous system outside the brain and spinal cord that connects to the CNS to gather sensory information
The somatic nervous system involves voluntary responses, and relay messages from your 5 senses to the CNS
The autonomic nervous system is the part of the nervous system responsible for the control of bodily functions, and involuntary actions
The parasympathetic nervous system a division of the autonomic nervous system and it is the system that conserves energy, increases gland activity, and relaxes sphincter muscles
The sympathetic nervous system is a division of the autonomic nervous system and it controls all the fight of flight responses
Sensory neurons are nerve cells responsible for converting external stimuli from the organism's environment into internal electrical impulses.
Interneurons are neurons that transmit impulses between other neurons, and allow for communication between sensory or motor neurons and the CNS
Motor neurons are nerve cells that form part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland
Neuromuscular junctions are chemical synapses formed by the contact between a motor neuron and a muscle fiber. At the neuromuscular junction a motor neuron is able to transmit a signal to the muscle fiber causing muscle contraction
Acetylochine is the neuro transmitter at neuromuscular joints that causes our skeletal muscles to contract and regulates our endocrine system
Norepinephrine is an organic chemical that functions in the brain and body as a hormone and neurotransmitter. Epinephrine is a hormone that is used to help life threading allegorical reactions, and in the brain it is used as a neurotransmitter.
Synapse is a junction between 2 nerve cells consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter
White matter is composed of bundles of nerve cell projections which connect various gray matter areas of the brain to each other and carry nerve impulses between neurons
Gray matter is a major component of the CNS consisting of neuronal cell bodies, and it is where all the synapses are
The cerebral cortex is the outer layer of the cerebrum that is composed of folded gray matter and plays an important role in consciousness
The lobes of the brain are the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. They are associated with different functions.
The limbic system is consisted of the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus. Each structure has a different function ranging from emotion to memory
