Want to know a fun and systematic way to remember the origins, insertions and actions of levator scapulae, rhomboideus minor and rhomboideus major? Watch and learn as Leslie Samuel discusses how to remember the origins, insertions and...

In this video, Leslie Samuel shows us the six intrinsic shoulder muscles -- deltoid muscle, supraspinatus, infraspinatus, teres minor, teres major, and subscapularis. Enjoy!

In this video, Leslie tells more about the first of six intrinsic shoulder muscles, the deltoid muscle. Furthermore, he gives us a great way of remembering the muscle's origin, insertion, and action by using what we have learned in...

In this video, Leslie Samuel discusses three more of the six intrinsic shoulder muscles -- infraspinatus, supraspinatus, and teres minor. They've been grouped this way to help you easily remember their insertions. How? Watch and learn...

In this video, Leslie Samuel talks about the intrinsic shoulder muscles, which are Supraspinatus, Infraspinatus, subscapularis, teres major and minor, and deltoideus. These are innervated by the suprascapular, upper and lower subscapular...

The muscles of the arm are the Biceps brachii, corachobrachialis, brachialis, and triceps brachii muscles. What are the nerves that innervate them? That's what Leslie Samuel talks about in this video. Turns out - there are only two - the...

In this video, Leslie talks about the main arteries that supply the Upper Extremities, which includes the subclavian, axillary, brachial, radial and ulnar arteries. The branches that come off those arteries will be discussed in later...

In this video, Leslie talks about the muscles of the anterior compartment, their innervation and function/action. These muscles include the Biceps Brachii, Coracobrachialis and Brachialis. The innervation is the musculocutaneous nerve...

In this video, Leslie talks about the function and innervation of the anterior compartment of the forearm and then the 5 muscles in the superficial layer of that compartment. These muscles include Pronator teres, flexor carpi radialis,...

Since we already covered the superficial muscles of the anterior forearm, it's time to get deep and talk about muscles like Flexor digitorum profundus, flexor pollicis longus and pronator quadratus. These also function in flexion of the...

In this video, I go over the content I covered in the last 2 videos. I basically review the muscles, innervation and functions of the muscles of the anterior forearm. This is a good review video, but I would highly recommend for you to...

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...

In this episode, Leslie Samuel talks about the four pectoral muscles -- pectoralis major (the main muscle most people refer to as the chest muscle), pectoralis minor, subclavius, and the serratus anterior. Furthermore, Leslie talks about...

In this video, Leslie Samuel talks about the fourth pectoral muscle. Learn why it's called serratus anterior and know more about its origin and insertion. Also, this muscle not only stabilizes the scapula but does a lot more. Watch to...

In this video, Leslie Samuel guides us in reviewing the four pectoral muscles with their origins, insertions and actions.

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.

Mean Arterial Pressure is Cardiac Output times Peripheral Resistance. That means if there's a change in Peripheral Resistance, that will result in a change in Mean Arterial Pressure. In this video, Leslie gets into the topic of...

Has science gone too far? Well, it has created these bizarre creatures. From super buff cows to featherless chickens, these are the creepiest, freakiest animals to ever come out of labs.
