Simply put, your triceps (or triceps brachii) is a large muscle found on the back of your upper arm. It consists of three integral parts – the medial, the lateral and the long head, all of which aid in movement contraction. (2) Importantly, this muscle group is responsible for the extension of the elbow joint, which in turn, allows you to straighten your arm. Triceps Anatomy As mentioned, the triceps brachii muscle has three heads, all of which have their origin. These components come together to form the muscle group, providing support to the exterior of the arm and furthering movement of the elbow joint. • Medial– Thishead arises proximally in the humerus, just inferior to the groove of the radial nerve; from the dorsal (back) surface of the humerus; from the medial intermuscular septum. • Lateral– As Platzer writes in Color Atlas of Human Anatomy (3), the lateral arises from the dorsal surface of the humerus, lateral and proximal to the groove of the radial nerve, from the greater tubercle down to the region of the lateral intermuscular septum • Long Head– This element arises from the infraglenoid tubercle of scapula. This element extends distally anterior to the teres minor and posterior to the teres major. Function The main function of the triceps is to allow movement and extension of the elbow joint. As such, ...

The triceps is the large muscle on the back of your upper arm that lets you straighten and extend your arm at the elbow. It is called the triceps because it’s made up of three parts (called muscle bellies). Pain or discomfort in the triceps can have a number of causes, but often means you have tears of the muscle fibers. They can be microtears, causing soreness, or larger tears, causing strains. You may also get triceps tendonitis and tendinopathy. The tendon is the cord-like structure that connects the triceps muscle to the bone at the elbow. Tendonitis is inflammation and pain of this tendon, which happens with repetitive motion against resistance. Tendinopathy is a chronic condition that eventually damages the tendon. The tendon can also rupture, a more serious and painful triceps tendon injury. Causes 1. Overuse or overexertion Symptoms • Dull achy pain over the entire triceps muscle • Both contracting the muscle (straightening the arm) and relaxing the muscle (bending the arm) may worsen the feeling of soreness. • Soreness may take 1 to 2 days to set in after you overexerted it and usually lasts just a few days. Triceps soreness is caused by micro...

FYI: But, you're likely neglecting the triceps, which are a minor muscle group but are key to overall fitness. "The triceps are a super, super important muscle group," says Jacqueline Kasen, CPT. "It stabilizes your your arms and your shoulders. It also helps increase like range of motion. So if you're strong there, triceps also help support chest, back, and shoulders." Meet the experts: What are the triceps muscles? Your triceps, which run along the backs of your upper arms, actually consist of three muscles—the long head, medial head, and lateral head—hence "tri." Together, these muscles help you extend your elbows and straighten your arms—and assist in chest-dominant exercises, like those infamous yogi pushups. There are different exercises that emphasize different parts of your triceps, so it's important to incorporate a variety of triceps exercises into your workout routine in order to build well-rounded strength. Triceps Workout Tips If you want to sculpt all 360 degrees of your It is possible to grow the size of your triceps (which can help make them pop) with regular targeted tricep workouts, Holly Roser, CPT, says. “Focus on full-body strength training and adding these triceps moves into your plan three days per week,” she recommends, adding that three sets of 8 to 15 reps is best. “You know you’re using the correct resistance when the last two reps seem almost impossible to finish.” You can effectively train the triceps in as little as two upper body-focused stre...

Share on Pinterest Triceps stretches are arm stretches that work the large muscles at the back of your upper arms. These muscles are used for elbow extension and to stabilize the shoulder. The triceps work with the biceps to perform most strong forearm movements. They’re one of the most important muscles for developing upper body strength, which is especially important as you age. Triceps stretches increase flexibility and can help prevent injuries. Always stretch to the degree that is comfortable without going beyond your limits. This will help you gain the most benefits and prevent injury. It’s also important to warm up and loosen your muscles before stretching them. Try a simple, Stretching can be done on its own or before or after athletic activity. Keep your breath smooth and natural throughout your routine and avoid bouncing. Here are four triceps stretches you can try at home. • Lift your shoulders up toward your ears and then draw them down and back. • Extend your right arm to the ceiling, then bend at the elbow to bring the right palm toward the center of your back, resting your middle finger along your spine. • Use your left hand to gently push your elbow in toward the center and down. • Hold this stretch 30 seconds for three to four repetitions on each side. • Start in the same position as the overhead triceps stretch, holding a towel or strap in your right hand. • Bring your left elbow down along your side body and reach your hand up to hold the bottom of the t...

The biceps and triceps muscles are the major flexors (biceps) and extensors (triceps) of the arm at the elbow joint. The biceps also play a very important role in rotating your forearm during activities such as turning a screwdriver or doorknob. Each of these muscles starts out as tendons near the shoulder, transition to muscles in the middle of the upper arm, then turn back into tendons near the elbow. They can be injured at any of these locations, but they are most commonly injured where the tendon inserts onto the bone at the elbow. These injuries are very common, and they typically occur after a sudden, forceful movement such as catching something that is falling or quickly lifting a heavy object. Next

Heading out the door? Read this article on the new Outside+ app available now on iOS devices for members! Many daily activities–steering a car, typing on a keyboard, chopping vegetables for dinner, even hugging someone you love–are forward- reaching movements. Even in yoga practice, you’re often stretching your arms out in front or reaching up overhead. That means you don’t get much of a triceps workout. But these muscles deserve your attention, says Richelle Ricard, author of Anatomy of the triceps The triceps brachii is muscle group with three parts. The whole unit attaches at the top of the ulna. The medial and lateral heads of the muscle originate at the posterior of the humerus. The long head originates at the lower edge of the scapula. (Illustration: Sebastian Kaulitzki/Science Photo Library) Your triceps are involved in any activity that requires you to reach back, pull something toward you, or reach up and pull down. But our modern lifestyle doesn’t call on these muscles very often. “We aren’t pulling nets out of the water. We’re not climbing trees and pulling ourselves up in space, so triceps aren’t getting exercised,” Ricard says. There are yoga poses that engage and strengthen the these muscles and help stabilize your arm and elbow so that you can safely practice postures such as Avoiding injury Ricard offers some safety cues that you don’t hear often in yoga class. One is to avoid locking your elbows in any straight-armed, weight-bearing postures....

It contains four muscles – three in the anterior compartment (biceps brachii, brachialis, coracobrachialis), and one in the posterior compartment (triceps brachii). In this article, we shall look at the anatomy of the muscles of the upper arm – their attachments, innervation and actions. Anterior Compartment There are three muscles located in the anterior compartment of the upper arm – biceps brachii, coracobrachialis and brachialis. They are all innervated by the musculocutaneous nerve. A good memory aid for this is BBC – biceps, brachialis, coracobrachialis. Arterial supply to the anterior compartment of the upper arm is via muscular branches of the brachial artery. Biceps Brachii The biceps brachii is a two-headed muscle. Although the majority of the muscle mass is located anteriorly to the As the tendon of biceps brachii enters the forearm, a connective tissue sheet is given off – the bicipital aponeurosis.
