to contract. Muscle is formed during embryonic development, in a process known as myogenesis. Muscle tissue contains special contractile proteins called...

formation of skeletal muscular tissue, particularly during embryonic development. Muscle fibers generally form through the fusion of precursor myoblasts into...

The cremaster muscle is a paired structure made of thin layers of striated and smooth muscle that covers the testicles and the spermatic cords in human...

Muscle contraction is the activation of tension-generating sites within muscle cells. In physiology, muscle contraction does not necessarily mean muscle...

A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal. In humans and other vertebrates there are three types:...

for athletic, occupational, and functional performance as well as muscle development, the barbell bench press is frequently used. The person performing...

Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres. The presence of sarcomeres manifests as a series...

Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, is the elicitation of muscle contraction...

abnormal development of muscles and connective tissue in the womb. Contractures develop usually when normally elastic tissues such as muscles or tendons...

Smooth (soft) muscle is one of the three major types of vertebrate muscle tissue, the other being skeletal and cardiac muscle. Nonetheless, it is found...

A muscle car is an American-made two-door sports coupe with a powerful engine, generally designed for high-performance driving. In 1949, General Motors...

deficiency in muscle development and increase of fat; on the other hand, smaller than normal amounts of myostatin greatly increase natural muscle mass, strength...

Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the other being cardiac muscle and smooth muscle. They...

extraocular muscles, or extrinsic ocular muscles, are the seven extrinsic muscles of the eye in humans and other animals. Six of the extraocular muscles, the...

Hypotonia is a state of low muscle tone (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength. Hypotonia is...

Occipitofrontalis muscle Temporoparietalis muscle Procerus muscle Nasalis muscle Depressor septi nasi muscle Orbicularis oculi muscle Corrugator supercilii muscle Depressor...

jaw muscles. The sagittal crest serves primarily for attachment of the temporalis muscle, which is one of the main chewing muscles. Development of the...

Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth...

Muscle hypertrophy or muscle building involves a hypertrophy or increase in size of skeletal muscle through a growth in size of its component cells. Two...

a muscle fibril or sarcostyle) is a basic rod-like organelle of a muscle cell. Skeletal muscles are composed of long, tubular cells known as muscle fibers...
