BIOL 252 Exam 3 Questions And Answers All Correct A _________ with a __________Diameter carries electrical impulses the fastest Myelinated, Large The finger-like projections extending from the neuron's cell body that are most frequently the site of stimulation and formation of graded potentials are called Dendrites Sense When a stimulus activates its specific sensory receptor. Perceive The process of your brain interpreting all the stimuli at a given time​ Receptors can either Adapt fast or slowly. If they do so quickly, they are called Tonic receptors, if they do so slowly, they are called Phasic receptors.​ general senses include:​ (Consciously ) ​ Consciously perceived:​ Touch​ Pressure​ Stretch​ Heat​ Cold​ pain​ Consciously perceived:​ Touch​ Pressure​ Stretch​ Heat​ Cold​ pain​ general senses (unconscious) Blood Pressure​ Blood composition​ Stretching of viscera​ Oxygen​ pH​ 5 special senses Olfaction (smell)​ Gustatory (Taste)​ Sight​ Auditory (hear)​ Equilibrium (Balance)​ ​Exteroceptors = primarily sense stimuli that are coming from the outside.
