Name the fixator muscles in a bicep curl?
since the bicep curl is a flexion of the forearm at the elbow, the biceps brachii and brachialis are mainly used, especially in the supinated position. a prone bicep curl uses brachialis and brachioradialis more. the biceps brachii function is much less, since it is also a forearm supinator, so it is deactivated in the prone position.
the triceps brachii are the antagonistic muscle group are not not involved in the bicep curl. the triceps extend the forearm at the elbow.
Where is the longest muscle in your body?
Longest muscle is there in your thigh. It is sartorius. It goes from your pelvic bone to leg bone.
How do the muscles work in the bicep curl?
The biceps are a grouping of muscle fibers that expand and contract one way. When you do a bicep curl, the muscles are lengthened under tension. There are thee phases to the curl. The first phase is a slow lowering (eccentric-lengthening) of the weight down to a parallel positioning with the ground. This should be a controlled 3-5 second movement. It should burn but not injure. Use appropriate weight. The 2nd phase is isometric. It's when the muscle neither expands nor contracts, but holds the weight parallel to the floor. 2 second hold...Explode into concentric motion. This is where you lift the weight and the bicep shortens. This is should be a 1 count tempo of intense movement. The ideal tempo is 4-2-1. Four seconds down, hold 2 seconds, explode up. Take rest intervals of 45 seconds to one and a half minutes between sets of 8-12 reps. Don't rock your shoulders or throw the weight up. Your biceps should be the focus.
Your muscles grow as a result of fatigue and recovery, where your muscle builds back up stronger.
The structure of the heart is very complex. Cardiac myocytes and intercalated discs follow the function of cardiac muscle tissue and the heart make up part of this very complex system
What part of body has involuntary muscles?
There are cardiac, smooth, and skeletal. Both cardiac and smooth are involuntary. Skeletal is voluntary. Skeletal muscles are the muscles you use to move your bones. You do these things voluntarily, like raising your arm. Skeletal muscle tires out quickly. Cardiac muscle is only found in your heart. This muscle type keeps your heart running and does not tire.
What organ system do the muscles in the arm and leg belong to?
If what you mean is; what muscles are found in organs, then the answer is smooth muscle.
Smooth muscle is an involuntary kind of muscle, in other words, you are unable to control it consciously. Smooth muscle generally lines the lumen of ducts and arteries. In arteries, this means that blood pressure can be maintained throughout the body. In ducts, they act like someone squeezing an old tube of toothpaste to try and get the last bit out.
There is also a particular kind of muscle called cardiac muscle, which is found in the heart. This kind of muscle contracts to a 'beat' set by the sino-atrial node (SAN) in order to force blood out of the atria and ventricles into the aorta.
How do you work on your biceps without weights?
Start by using a light weight, maybe 2.5kg and do arm curls. 5 sets of 20 reps an evening would be a good place to start. Increasing the amount of reps by 5 and the sets by 1 every week. Once you reach 10 sets of 45 reps, increase the weight by 2.5kg every time you start again. So by the end of week 20 you should be able to lift 10kg for 10 sets of 45 reps. Remember to eat plenty of proteins and carbs.
What smooth muscles are controlled by autonomic nerves and hormones?
are multiunit muscles.
single unit muscle
What joint action occurs when the biceps muscles contract concentrically?
The bicep muscle relaxes. It is vice-versa when the bicep muscle contracts.
What is the muscle in your toe called?
There are seven muscles that control the toes. The "big toe" is controlled by the flexor hallucis longus, the flexor hallucis brevis and the abductor hallucis. The three middle toes are controlled by the flexor digitorum brevis and the extensor digitorum brevis. The last and smallest toe is controlled by the flexor digiti minimi and the abductor digiti minimi.
What is Rotator cuff tendinopathy?
when the supraspinatus tendon becomes compressed by the greater tuberosity when the arm is adducted and abducted. This restricts the blood supply, creates avascular zone and promotes the tendinopathy. Can be the result of keeping the shoulder in one position over a period of time, sleeping on the shoulder every night, or participating in activities that require extending the arm over the head
What make the skeletal muscle bright red?
Because muscles need a lot of ATP for muscle contraction and it needs oxygen to make ATP, it has its own form of hemoglobin called myoglobin. The binding of oxygen to hemo(myo)globin is what gives the characteristic red color in both RBCs and muscle tissue.
Breathing, digestion and heartbeat are all considered automatic body functions, because you don't have to think about them. You can hold your breath, or hyperventilate, but you don't have to "remember" to breathe.
Muscle inserts into the mastoid process?
Posterior Belly of Digastric Muscle (innervated by CN VII) Facial nerve
Sternocleidomastoid (innervated by CN XI) Spinal accessory nerve
Longissimus Capitis (innervated by dorsal rami of C3-C8 spinal nerves)
Splenius Capitis (innervated by dorsal rami of middle cervical spinal nerves)
Connective tissue ensheathing a bundle of muscle cells?
Connective tissue covering surrounding individual muscle fibers is known as deep fascia This tissue protects the muscle and helps it keep it's form.
The heart muscle is composed of a specialized type of muscle tissue called?
the cardiac muscle also known as myocardium is a muscular tissue of the heart
What muscle is The triangular muscle that helps to lift your arm above your head is?
That is the deltoidus muscle, or simply 'deltoid' muscle. In the Greek alphabet, the letter 'delta' is a triangle shape.
The muscles that allow a person to flex the head on the chest are called?
Does the sternocleidomastoid (SCM) muscle cause a pull, and tingling sensation in my thighs and legs? I get this pull and tingling sensation in my thighs and legs when I lower my head toward my chest only. Why is that?
