Anatomy & Physiology of a Neuron (Neural) Structure Review
RegisteredNurseRN・2 minutes read
Neurons are excitable cells with special characteristics, including a long lifespan, inability to divide, and high metabolic rate. They consist of various components like dendrites and axons that transmit electrical signals and are important for understanding brain function.
Insights
- Neurons are unique cells with a long lifespan, inability to regenerate, and high energy demands, making them crucial for transmitting electrical signals in the body.
- Understanding the structure of a neuron, including components like dendrites and axons, is essential for grasping how these cells function in transmitting signals within the nervous system.

"Neuron Structure and Function Explained"
- Neurons are excitable nerve cells that transmit electrical signals, while support cells wrap around and surround the neuron.
- Neurons have three special characteristics: longevity of over 100 years, inability to divide or be replaced, and a high metabolic rate requiring continuous oxygen and glucose.
- The structure of a neuron includes the cell body (Soma), nucleus, chromophilic Nissle bodies, lysosomes, mitochondria, neurofibrils, dendrites, initial segment, axon hillock, axon collateral, axon, terminal branches, axon terminals, and Schwann cells.
- Dendrites conduct electrical signals towards the cell body, while the axon conducts signals away from the neuron.
- Quiz questions test understanding of neuron characteristics and structure, with answers emphasizing key terms like cell body and specific functions of neuron components.
