PSYB64H3 Chapter Notes - Chapter 3: Neurofibrillary Tangle, Endoplasmic Reticulum, Unipolar Neuron
Document Summary
Week 3 may 19 h , 2015. These neurons are typical of invertebrate nervous systems. In vertebrates, unipolar cells may be found in the sensory systems and in the autonomic. Ns: bipolar neuron: a neuron with two branches: one axon and one dendrite. Play important roles in the sensory systems, including the retina of the eye. Von economo neuron (ven): appear to have developed recently in primate evolution. Found in humans and great apes but not in lesser apes and monkeys. Occur only in the anterior cingulate cortex (acc) and in the junction of the frontal lobe and insula area of the temporal lobe. Designed to provide fast, intuitive assessments of complex situations: multipolar neuron: a neuron that has multiple branches, usually one axon and numerous dendrites. The most common structural type of neuron in the ns. Pyramidal cells: are located in the cerebral cortex and hippocampus.
