As with all tissues dependent on a vascular supply, muscles depend on red blood cells to transport oxygen to them. Red blood cells, in turn, rely on an oxygen transport protein called hemoglobin to carry oxygen to all parts of the body.
A:The body parts involved in hip extension when climbing stairs are the torso and lower back, opposite leg, knee and ankle, and hip joints. Hip extension during stair climbing occurs when the opposite leg is raised to the next step.
A:MedlinePlus explains that the human body has three different types of muscles: skeletal, cardiac and smooth. These muscle groups have different functions, are located in different parts of the body and have different structures.
A:A static (or isometric) contraction occurs when a muscle generates force while the joint angle remains the same. An example would be what happens when a person pushes against a wall. The muscles contract but the joint remains unmoved. A dynamic (or isotonic) contraction occurs when the force generated by the muscle causes movement in the joint. Dynamic contractions occur during most physical activities.
A:The muscular system consists of approximately 700 muscles that belong to one of three distinct categories: skeletal, smooth or cardiac. Skeletal muscles are attached to the body's skeleton and assist it in moving. Smooth muscles are found in the internal organs and help maintain normal functions such as bladder control. Cardiac muscle is only found in the heart.
A:Despite myths hailing it to be the strongest single muscle in the body, the human tongue is actually comprised of eight different muscles, according to the Richmond Smile Center. The muscles that comprise the tongue are skeletal muscles.
A:The major muscle groups in the body are the abdominal muscles, biceps, deltoids, erector spinae, gastrocnemius, soleus, gluteus, hamstrings, latissimus dorsi, rhomboids, obliques, pectoralis, quadriceps, trapezius and triceps. Each muscle group contributes to a variety of different functions, such as walking, climbing and sitting.
A:The scientific name of the anterior thigh muscles is the quadriceps femoris. The other muscles in the thighs are called the adductors, which form the inner thigh, the hamstrings, which are at the back of the thighs, and the abductors, which are found on the outer thighs.
A:According to Clinical Anatomy For Dummies, there are a total of 18 intrinsic muscles that work to move each hand. These muscles are in three groups: the thenar muscles, the hypothenar muscles and the interosseous muscles and the lumbricals.
A:The stapedius muscle, which is the shortest muscle in the human body (at a mere millimeter in length), holds the stapes in place inside the tympanic cavity of the ear. The stapedius works in conjunction with the smallest bone in the body to aid the function of hearing.
A:According to Yoga Journal, sitting cross-legged requires flexibility in the hip joints, back and inner thighs, and pelvis. These muscles are all very strong and can take some coaxing before stretching and relaxing enough for this to be a comfortable seated position.
A:The standing lateral raise primarily works the lateral deltoid muscles, which are the muscles found on the sides of the shoulders. Synergists include the middle and lower trapezius and the anterior, or front, deltoid muscles.
A:Women are incapable of developing their muscles, including the biceps, to the extent of most men due to their lack of testosterone. A woman's biceps, however, can still grow larger and stronger through exercises, such as the dumbbell curl and the chin-up that target this muscle and related muscles.
A:The bicep, like other muscles, is primarily controlled by the cerebrum, a section of the brain located just above the brain stem and the cerebellum. The peripheral nervous system relies on the cerebrum to send signals to the bicep's short and long heads so that they function as a single muscle as the bicep contracts during the curl.
A:Enthesopathy of the hip is an arthritic disorder in the sockets of the hip bone that affects the tendons and ligaments that are attached there. This means that the connections are not working correctly or are damaged in some way, creating problems with the connecting tissues between the hips and other bones. This causes pain or difficulty while moving or walking.
A:As with all tissues dependent on a vascular supply, muscles depend on red blood cells to transport oxygen to them. Red blood cells, in turn, rely on an oxygen transport protein called hemoglobin to carry oxygen to all parts of the body.
A:The whole body is involved in a baseball swing, with legs, forearms, wrists, abdominal muscles, hips and lower back muscles playing the most important roles, according to Bob Alejo for BodyBuilding.com. Hitting coaches concentrate on strengthening these and other muscles with weight training, calisthenics and resistance-based exercises.
A:The quadriceps, also known as the thigh muscles, move the knee and the hip, and they prevent the knee from buckling. The quadriceps are engaged when doing squats, climbing stairs, standing up and walking.
A:Newton's second law of motion states that the force that an object exerts is equal to that object's mass times its acceleration. The amount of force that individuals can exert is directly proportional to their mass and the speed at which they are moving.
A:Six extraocular muscles allow the eyeballs to move: the inferior, superior, lateral and medial rectus muscles together with the inferior and superior oblique muscles. Vision Aware adds that the muscles that move the eyeballs are attached to the sclera, a white outer coating that covers the eyeball.
