Axon thin process of uniform diameter - impulse generators and conductors that transmits nerve impulses AWAY from cell body Hillock "little hill" Schwann Cell bead like- wrapped around axon, made of fat Terminal Butons talks to dendrites of another cell What chemicals do neurons use for communication and where is it located? neurotransmitters - terminal butons Function/ location of Somatic motor neuron Reflexes. Receptors that pick up on stimulus afferent pathways via sensory neurons- passes into the CNS - interneuron Stages of Arc Reflex 1. receptor 2. Sensory Neuron 3. integration center 4. motor neuron 5. effector Receptor site where stimulus acts - located on terminal end of peripheral process of sensory neuron sensory neuron transmits afferent impulses to CNS Frontal Lobe primary motor cortex - motor movement Parietal Lobe conscious awareness of general somatic sensations, spacial awareness, understanding speech occipital lobe visual cortex temporal lobe recognition, auditory cortex, olfactory cortex largest region of brain cerebrum 2nd largest region of brain cerebellum Sulcus shallow grooves - valley Gyrus between sulci, twisted ridges of tissue Hypothalamus regulates thirst, body temperature and hunger corpus colossum BIG C. attaches hemispheres and buffers messages Blood Brain Barrier helps limit exposure of things to neurons CSF produced in Coroid Plexus Hindbrain structures Cerebellum Pons Medulla Oblongata Brian stem medulla oblongata pons midbrain reaching all the way to the spinal cord Pineal Gland in the epithalamus- secretes melatonin with darkness Arbor Vitae cerebellum - tree of life - Schwann cells Meningeal membranes Dura , Pia, Arachnoid Mater what separates the cerebrum from the cerebellum transverse fissure location of the neural center that controls heart rate and respiration medulla oblongata
