The bench press is an upper-body strength-training exercise that consists of pressing a weight upwards from a supine position. The exercise works the pectoralis major as well as the supporting chest, arm, and shoulder muscles such as the anterior deltoids, serratus anterior, coracobrachialis, scapulae fixers, trapezii, and the triceps. A barbell is generally used to hold the weight, but a pair of dumbbells can also be used.
The torso or trunk is an anatomical term for the central part or core of many animal bodies from which extend the neck and limbs. The torso includes: the thoracic segment of the trunk, the abdominal segment of the trunk, and the perineum.
A push-up is a common calisthenics exercise beginning from the prone position, or the front leaning rest position known in the military. By raising and lowering the body using the arms, push-ups exercise the pectoral muscles, triceps, and anterior deltoids, with ancillary benefits to the rest of the deltoids, serratus anterior, coracobrachialis and the midsection as a whole. Push-ups are a basic exercise used in civilian athletic training or physical education and commonly in military physical training. They are also a common form of punishment used in the military, school sport, or in some martial arts disciplines.
The pectoralis major is a thick, fan-shaped muscle, situated at the chest (anterior) of the human body. It makes up the bulk of the chest muscles and lies under the breast. Below the pectoralis major is the pectoralis minor, a thin, triangular muscle. In sports as well as bodybuilding, the pectoral muscles may colloquially be referred to as "pecs", "pectoral muscle" or "chest muscle" due to its being the larger and most superficial muscle in the chest area.
The pectoralis minor is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major in the human body.
The anatomy of the domestic cat is similar to that of other members of the genus Felis.
In human anatomy, the lateral thoracic artery is a blood vessel that supplies oxygenated blood to the lateral structures of the thorax and breast.
Poland syndrome is a birth defect characterized by an underdeveloped chest muscle and short webbed fingers on one side of the body. Short ribs, less fat, and breast and nipple abnormalities may also occur on that side. Typically the right side is involved. People generally have normal movement and health.
The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid. Some mammalian species have only the scapula.
The lateral pectoral nerve arises from the lateral cord of the brachial plexus, and through it from the fifth, sixth, and seventh cervical nerves.
The sternalis muscle is an anatomical variation that lies in front of the sternal end of the pectoralis major parallel to the margin of the sternum. The sternalis muscle may be a variation of the pectoralis major or of the rectus abdominis.
The ventral ramus is the anterior division of a spinal nerve. The ventral rami supply the antero-lateral parts of the trunk and the limbs. They are mainly larger than the dorsal rami.
A Cable fly or Cable flye is a strength training exercise in which the hand and arm move through an arc while the elbow is kept at a constant angle. Flies are used to work the muscles of the upper body. Because these exercises use the arms as levers at their longest possible length, the amount of weight that can be moved is significantly less than equivalent press exercises for the same muscles .
Due to this leverage, fly exercises of all types have a large potential to damage the shoulder joint and its associated ligaments and the tendons of the muscles connecting to it. They should be done with caution and their effects first tested while using very light weights; which are gradually incremented after more strength is gained.
The dip or push-ups is an exercise used in strength training. Narrow, shoulder-width dips primarily train the triceps, with major synergists being the anterior deltoid, the pectoralis muscles, and the rhomboid muscles of the back. Wide arm training places additional emphasis on the pectoral muscles, similar in respect to the way a wide grip bench press would focus more on the pectorals and less on the triceps. Proper form is important to avoid putting undue stress on the wrists.
Targeted reinnervation enables amputees to control motorized prosthetic devices and to regain sensory feedback. The method was developed by Dr. Todd Kuiken at Northwestern University and Rehabilitation Institute of Chicago and Dr. Gregory Dumanian at Northwestern University Division of Plastic Surgery.
