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 accessory, thoracodorsal and dorsal scapular nerves, and how they innervate the extrinsic back/shoulder muscles, which include trapezius, Latissimus dorsi, Levator Scapulae, rhomboid minor and...

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...

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, I talk about the Triceps Brachii muscle, which is found in the posterior compartment of the arm, the radial nerve (innervation) and its function as a flexor of the forearm (elbow flexion).

In this video, I talk about all the boundaries of the cubital fossa. This includes pronator teres, brachioradialis, the imaginary line between the two epicondyles, brachialis, the bicipetal aponeurosis, median cubital vein and the medial...

In this video, I talk about the 3 structures that are found within the cubital fossa: 1. The Tendon of Biceps Brachii, 2. The Brachial Artery (used for...

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, 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...

Smaller than the pectoralis major, the pectoralis minor functions to stabilize the scapula. In this episode, Leslie Samuel shows you that this muscle originates from the anterior aspect of the 3rd, 4th, and 5th ribs and inserts into the...

In this episode, Leslie Samuel talks more about the first of four pectoral muscles, the pectoralis major. Also learn about the origin, insertion and action of the clavicular and sternocostal portions of pectoralis major.

In this video, Leslie Samuel shows the origin, insertion, and action of the smallest pectoral muscle, the subclavius muscle. Also, learn how the name of this muscle can help to remember about its location. This and much more!

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.

In this episode, Leslie Samuel teaches us about the complex origins, insertions, and actions of the trapezius muscle and latissimus dorsi. Learn how to identify the different actions that each of these muscle does. This and much more!

What would the skeletal system be without muscles to move our bones. Muscles are an essential part of what makes us humans and in this lecture, I talk about the three types of muscle, and more importantly, how they work. How does muscle...

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...

Anatomy and functions of the muscles of the upper arm.

Attachments, innervation and function of the flexor pollicis longus muscle.

In this full-lecture video, we discuss the theory, contraindications/precautions, specific uses, and techniques by which we can apply heat as a therapeutic modality along with any relevant associated parameters.

In this video, we explore the concept of cold therapy and its benefits for muscle recovery after intense physical activity. We discuss two methods of cold therapy: applying ice to specific muscles and taking a cold bath. We also...
