Neurons

Neurons. Neurons and neuroglia (multiple sclerosis and neuroglia) Where are neurons in the body? Types of neurons and their functions How do neurons work? Action potentials Synapses. Cell body with nucleus Axon (carries message) Note Schwann cells Dendrites (bring stimulus to cell body)

Neurons

Neurons. I bet your neurons are all fired up now!. The Nervous System. NEURON = 1 cell. Nerve = a bundle of neurons. Types of Neurons. Efferent (Motor) Neurons - carry outgoing messages from the brain and spinal cord to the muscles and glands

Neurons

Neurons. Vary in size and structure, but have common features: Cell Body Dendrites Axon Mature neurons do not divide, but neural stem cells can divide and form neurons or neuroglial cells. 1. Cell Body.

Neurons

Unit 2 – Biology of Psychology. Day 1 -. Neurons. Because when you say someone’s “wires are crossed” you might actually be correct. Objectives. Understand the relationship between “Biology” and “Psychology” Identify the two major systems that affect biological psychology

Neurons

Neurons. The fundamental neural circuit element Neurons come in many Shapes and sizes. Information flow in neuronal circuits is into dendrites. and then to the soma . and then through axons. to synapses. and onto the next cell. Therefore Information flow is directional.

Neurons

Neurons. Functional Organization of Neurons. Input zone (dendrites). Transmission zone (axon). Output zone (synapses). The Resting Potential. Almost all cells have a transmembrane electrical charge difference, with the inside roughly 50-100 mV negative relative to the outside.
