English

What you'll learn

  • • Describe the structure and function of the different neural systems including the autonomic, peripheral, somatosensory, motor, visual, auditory, neuro-endocrine, limbic and olfactory systems.
  • • Describe and give examples of neurological diseases arising from dysfunction or degeneration of brain regions and pathways studied
  • • In this course will learn about the brain and spinal cord, and how the peripheral nervous system consists of the nerves that extend to all the other organs in the body.

Course content

3 sections • 25 lectures • 1h 25m total length

  • Introduction of Nervous System1:46

    Explore how the nervous system maintains homeostasis with the endocrine system, using electrical signals for fast responses and hormones for slower effects, via sensory input, integration, and motor output.

  • Affrent & effrent nerves2:08

    Explore afferent and efferent neurons in the nervous system, detailing how afferent neurons carry sensory impulses toward the CNS and efferent neurons carry signals away from the CNS.

  • Organization of Nervous System0:59
  • Nerve Tissue0:59
  • Neuron8:45

    Explore the neuron’s structure and function, from the soma with nucleus and organelles to dendrites and axons, and how myelination and action potentials enable signaling at synapses.

  • Neuroglia3:58
  • Classification & properties of nerve fibre1:58

    The lecture classifies nerve fibers into A, B, and C by their properties and speed of conduction, detailing size (microns) and how conduction velocity varies with fiber type.

  • Electrophysiology0:37

    Explore electrophysiology, the study of the electrical properties of biological systems, and learn how researchers measure the electrical activity of neurons during action potentials.

  • Action Potential5:43
  • Nerve Impulses2:06

    Explore how nerve impulses trigger depolarization and calcium influx, prompting vesicle release of neurotransmitters into the synaptic cleft. Learn how transmitter binding to receptors generates excitatory and inhibitory synaptic potentials.

  • Receptor1:38

    Explore receptors as binding sites on membranes or inside cells that recognize signal molecules and initiate cellular responses, using the lock-and-key analogy to illustrate specificity.

  • Synapses2:19
  • Neurotransmitter0:50

    Explore how neurotransmitters, the chemicals of neuronal communication, are classified chemically, act like a key, and drive depolarization with excitatory transmitters like glutamate while GABA causes hyperpolarization.

Requirements

  • Basic Biology

Description

· This module will provide a detailed understanding of the structure and function of the nervous system.

· This anatomy course teaches you about the central and peripheral human nervous systems.

· In this course will learn about the brain and spinal cord, and how the peripheral nervous system consists of the nerves that extend to all the other organs in the body.

· Starting with nervous system development and then focusing on the adult nervous system, students will learn about the gross anatomy of the human brain and spinal cord and its constituent systems including autonomic, sensory, visual, auditory, somatosensory, and olfactory and limbic systems. Lectures will also be given about the vasculature, ventricles and CSF.

  • Neurons (specialized cells of the nervous system ) send signals along thin fibers called axons and communicate with other cells by releasing chemicals called neurotransmitters at cell-cell junctions called synapses.

  • Glial cells are non-neuronal cells that provide support and nutrition in the nervous system.

  • In humans, the nervous system consists of both the central and peripheral nervous systems.

  • The human central nervous system contains the brain, spinal cord, and retina.

The peripheral nervous system consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system
