How do muscles actually contract? There's a lot involved in the process. And in this video, we talk about muscle contraction at the molecular level. We'll discuss sarcomeres, actin, myosin, the muscle action potential and the roles of...

This video explains how our body responds to different stimuli through the nervous system. It covers the anatomy and function of nerve cells, nerve fibers, and the different types of neurons that make up the nervous tissue. The video...

Contents of the female pelvis, including the viscera and perineum.

In this video, my wife helps me to demonstrate how reflexes work at the level of the neurons. We look at both the Knee jerk and eye blink reflexes and the mechanism underlying both.

In this video, I talk about the medulla, pons and midbrain, the 3 parts of the brain stem and take a bried look at their functions.

In this video, Leslie Samuel talks about the anatomy and function of the cerebellum. He shows the peduncles and how they connect the cerebellum to the brainstem. He then talks about the 3 lobes and the regions of the Central Nervous...

Learning about the anatomy of the brachial plexus can be tough. But, it can be quite easy if you have the right pneumonics to guide you. Watch this video as Leslie Samuel makes it fun and easier to go through each of the roots, trunks,...

In this episode, I talk about the divisions of the nervous system and deal with terms like the Central and Peripheral Nervous Systems, Brain and Spinal Cord, Somatic and Autonomic Nervous System, Sympathetic and Parasympathetic Nervous...

The nervous system is the control center of the body. But how does it actually work? In this video, we discuss what the nervous system does, the divisions of the nervous system, and how certain functions (like vision and reflexes) work.

BioVid Episode 1 - An Introduction to the Nervous System. This is the first in a series of Videos teaching different...

BioVid Episode 2 - An Introduction to Neurons. In this video, I talk about what a neuron is, the parts of a neurons and then talk about the three types of neurons.

This brief video tutorial is Part 3/3 of a series on the Female Reproductive system. This tutorial focuses on the female orgasm (nerve pathways for stimulation and orgasm). 0:00. Introduction 1:16. Stimulation (Somatic sensation:...

In this video, we will discuss the anatomy and function of the withdrawal reflex.

The video provides an explanation of the nervous system, its components, and how they work together. The video explains how a stimulus is detected, converted into an electrical impulse, and travels along a sensory neuron to the CNS,...

This video tutorial covers the gray matter of the spinal cord.

This video tutorial provides an overview of the Autonomic Nervous System (ANS) and helps establish how neural crest cell migration contributes to understanding post-ganglionic neurons.

This is the fifth practice lesson set consisting of 24 Medical Terminology Practice Problems to help you bring together all the information you’ve learned from the Medical Terminology, The Basics lesson series and the Anatomy lesson...

Experts in neuroscience help us understand why the human brain is a marvel of structure and function. This video examines the interaction of the spinal cord and nerve endings which is a key part of the Central Nervous System. The cranial...

Professor Homayoon Kazerooni is a robotics engineer at the University of California, Berkeley with more than 40 patents to his name. His research on exoskeletons relies on more than just ingenuity and engineering expertise, it's also...

This video tutorial briefly covers the segmental organization of spinal cord, spinal nerve and vertebral levels. It discuss the principle of vertebrosegmental discrepancy.

The basic purpose of the Nervous System is to coordinate all of the activities of the body. It enables the Body to respond and adapt to changes that occur both inside and outside the body.The two major parts to the Nervous System...

We just learned all about how sensory information from the surroundings makes it to the brain, but once it's there, the brain has to then tell the body what to do to respond to its surroundings. This happens thanks to the sensorimotor...

Structure of the gray matter of the spinal cord in cross section.

Ouch! That hurt! When your baby brother bites your finger, how do you feel it? How do you know whatês hot or whatês cold? How can you tell if something is soft or scratchy or damp? Most of all, how do we feel pain? Weêre talking about...
