Human-robot hybrids are advancing quickly, but the applications aren't just for complete synthetic humans. There's a lot we can learn about ourselves in the process.

Hank tells us the story of the complicated chemical dance that allows our skeletal muscles to contract and relax.

Why do our muscles get tired and sore after exercise? Explore how our muscles function, and how you can exercise longer without experiencing muscle fatigue. -- You're lifting weights. The first time feels easy, but each lift takes more...

In this video Paul Andersen explains the basic anatomy of a neuron; including the dendrites, cell body, axon hillock, axon, and axon terminal. He also describes how neurons are classified both structurally and functionally.

In this video, Jonathan from the Institute of Human Anatomy discusses the decline in muscle mass as we age, some of the main reasons for this decline, and the best type of exercise and resistance training to help minimize this...

In this video we cover what the nervous system is, how it relies on nerve cells and synapses, and what a reflex arc is.

ALS, or Amyotrophic lateral sclerosis, is a rare disorder that involves the death of neurons that control voluntary muscles. Descriptions of the disease date back to the early 19th century. French neurologist Jean-Martin Charcot was...

This #shorts video tutorial tests spinal cord and spinal nerves (Part C). Ventral root, ventral ramus, dorsal root, dorsal ramus, spinal nerve trunk, cervical cord, thoracic cord, lumbar cord, sacral cord, ventral horn, lateral horn,...

This video provides an introduction to the nervous system and its key features. The speaker explains the role of the nervous system in allowing communication throughout the body using electrical impulses, and discusses the central...

Students will learn the three main types of neurons and how they travel through the body's nerve network. Diagrams explain how information is received using our sensory organs and then processed by the central and peripheral nervous...

Part 1 of 2 of excitation-contraction coupling | In this video, we discuss excitation-contraction coupling from events on the motor neuron axon all the way through opening of calcium channels in the sarcoplasmic reticulum (SR).

In this video, we discuss all steps of excitation-contraction coupling in skeletal muscle from events on the motor neuron axon all the way through cross-bridge cycling between actin and myosin.

DESCRIPTION



In this video we are going to look at measuring reaction times and how reaction times can be affected by differ

In this video, we explore the basic biochemical mechanism of neuronal death in amyotrophic lateral sclerosis or ALS.

In this video, we will discuss the events of Excitation-Contraction Coupling from the motor neuron action potential to release of Ca2+ from the sarcoplasmic reticulum (SR). **Part 2 Coming Soon

The video is a lesson on reflex arcs and the function of reflex actions in the nervous system. Using a hot pan as an example, the video describes how pain receptors in the skin detect a stimulus, which triggers a series of neuronal...

This tutorial covers the muscles (attachments, actions and innervation) of the superficial muscles of the back.

The video provides an overview of the nervous system, explaining what it is, how it works, and its different components. The narrator describes the function and role of sensory receptors, neurons (sensory, relay, and motor), and...
