Autonomic Nervous System- Effectors that are involuntary, heart, smooth muscle (viscera) in blood vessels and various glands are controlled by the autonomic nervous system. Axon- A nerve fiber that conducts a nerve impulse away from a neuron cell body. Central Nervous System- consisting of brain and spinal chord for the central nervous system. (CNS) Chromatophilic Substance- (Nissl bodies) Membranous sacs within cytoplasm of nerve cells that have ribosomes attached to their surfaces. Convergence - Nerve impulses arriving at the same neuron. Dendrite- Nerve fibers that transmits impulses toward a neuron cell body. Divergence- Spreading apart.

Effector- A muscle or gland that responds to stimulation. Facilitation- Sub threshold stimulation of a neuron makes it more responsive to further stimulation. Ganglion- A mass of neuron cell bodies, usually outside the central nervous system. Meninges- Located between the bone and soft tissues of the nervous system protects the brain and spinal chord. Membranes. Myelin- lipid-protein (lipo-protein) Neurilemma- Sheath formed from Schwanna cells on the outside of some nerve fibers. Neurotransmitter- Chemical that an axon end secretes to stimulate a muscle fiber to contract or a neuron to fire an impulse. Parasympathetic Nervous System- Peripheral nervous system, which controls skeletal muscle. Peripheral Nervous System- (PNS) the portion of the nervous system outside the central nervous system.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
