Types of Tissue Part 4: Nervous Tissue

Professor Dave Explains2 minutes read

The nervous system controls the body through neurons that transmit electrical impulses, with different types based on structure and function. Neurons generate electrical impulses through ion channels, with the system divided into central and peripheral components.

Insights

  • Neurons, the building blocks of the nervous system, play a crucial role in transmitting electrical signals throughout the body, with distinct structures and functions based on their type and location.
  • The nervous system is divided into two main components: the central nervous system, comprising the brain and spinal cord, and the peripheral nervous system, consisting of nerves spread throughout the body, enabling humans to control bodily functions through communication between neurons and the brain.

  • What are the components of neurons?

    Neurons consist of a central cell body, dendrites, and axons.

  • How does myelination affect signal transmission?

    Myelination increases the speed of signal transmission.

  • What are the different types of neurons based on function?

    Neurons can be sensory, motor, or interneurons.

  • What are the regions of a neuron responsible for signal transmission?

    Neurons have a receptive, trigger, conducting, and secretory region.

"Neurons: Building Blocks of Nervous System"

  • The nervous system allows humans to control their body through signals from the brain.
  • The nervous system is made up of neurons, which are cells that transmit electrical impulses.
  • Neurons have a central cell body, dendrites for receiving signals, and axons for transmitting signals.
  • Neurons can be myelinated, which increases the speed of signal transmission.
  • There are different types of neurons based on structure (unipolar, bipolar, multipolar) and function (sensory, motor, interneurons).
  • Neurons have a receptive region, trigger zone, conducting region, and secretory region.
  • Neurons generate electrical impulses through ion channels and changes in membrane potential.
  • The nervous system is divided into the central nervous system (brain and spinal cord) and peripheral nervous system (nerves throughout the body).
