  1. 2. neurons-Efferent neurons, also called motor neurons, are the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action
  2. 6. cortex- the layer of gray matter that covers the outside of the cerebral hemispheres in the brain and is associated with higher cognitive functions, such as language, learning, perception, and planning.
  3. 8. callosum-a large tract of nerve fibers running across the longitudinal fissure of the brain and connecting the cerebral hemispheres
  4. 10. and adaptability. The plasticity of the nervous or hormonal systems makes it possible to learn and register new experiences.
  5. 13. nervous system-one of the two divisions of the autonomic nervous system (ANS), the other being the parasympathetic nervous system.
  6. 16. lobe-one of the four main subdivisions of each cerebral hemisphere in the brain, lying immediately below the lateral sulcus on the outer surface of each hemisphere.
  7. 17. posterior of three bulges that appear in the embryonic brain as it develops from the neural tube.
  8. 18. nervous system-the portion of the nervous system innervating smooth muscle and glands, including the circulatory, digestive, respiratory, and reproductive organs.
  9. 19. are nerve cells and the basic building blocks of our entire nervous systems. The neurons act as sensors for all types of stimuli and communicate the stimuli throughout the body.
  10. 20. nervous system-one of two branches of the autonomic nervous system (ANS), the other being the sympathetic nervous system.

  1. 1. of a large number of chemicals that can be released by neurons to mediate transmission of nerve signals across the junctions (synapses) between neurons.
  2. 3. nervous system-controls all voluntary and involuntary muscles and glands. Essentially, the peripheral nervous system contains all your nerves and nerve bundles excluding the brain and spinal cord.
  3. 4. nervous system-any of a large number of chemicals that can be released by neurons to mediate transmission of nerve signals across the junctions (synapses) between neurons.
  4. 5. lobe-one of the four main lobes of each cerebral hemisphere of the brain, lying in front of the central sulcus.
  5. 7. lobe-one of the four main subdivisions of each cerebral hemisphere. It occupies the upper central area of each hemisphere, behind the frontal lobe, ahead of the occipital lobe, and above the temporal lobe.
  6. 9. specialized junction through which neural signals are transmitted from one neuron (the presynaptic neuron) to another (the postsynaptic neuron).
  7. 11. nervous system-CNS is a term that describes the brain and the spinal cord. This is a term you are probably familiar with since it is one of the most commonly used scientific terms.
  8. 12. lobe-he most posterior (rearward) subdivision of each cerebral hemisphere, roughly shaped like a pyramid and lying under the skull’s occipital bone. It contains several visual areas that receive and process visual stimuli, and it is involved in basic visual functions
  9. 14. neurons-Afferent neurons, also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain.
  10. 15. part of the brain that develops from the anterior section of the neural tube in the embryo, containing the cerebrum and the diencephalon.
