The fact that there are more than 600 muscles in the body can be quite intimidating. If you’re tired of all the big, comprehensive anatomy books, take a look at our condensed muscle anatomy reference charts, which contain all the muscle facts in one place organized into neat tables!

The temporal lobes: Located on either side of the brain, the temporal lobes play a role in numerous functions, including speech, scent recognition, and short-term memory. In this article, we will explore the many functions of muscle in the human body as well as its basic structure, types and classifications.Arthritis is a group of conditions affecting the joints. These conditions cause damage to the joints, usually resulting in pain and stiffness due to aging. Arthritis can affect many different parts of the joint and nearly every joint in the body. Muscles of the upper limbs, which include muscles of the shoulder, muscles of the arm, muscles of the forearm and muscles of the hand

Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain, it is known as involuntary muscle—it cannot be directly controlled by the conscious mind. The term “smooth muscle” is often used to describe visceral muscle because it has a very smooth, uniform appearance when viewed under a microscope. This smooth appearance starkly contrasts with the banded appearance of cardiac and skeletal muscles. Cardiac MuscleA tendon is a tough, flexible band of dense connective tissue that serves to attach skeletal muscles to bones. Tendons are found at the distal and proximal ends of muscles, binding them to the periosteum of bones at their proximal ( origin) and distal attachment ( insertion) on the bone. As muscles contract, the tendons transmit the mechanical force to the bones, pulling them and causing movement. Based on the type of tissue that holds the neighboring bones together and the range of motion they exhibit, joints can be classified into the following:

Strains: Muscle strains, or pulled muscles, occur when you overstretch muscle fibers. These injuries are usually the result of overuse. Severe strains can lead to partial or complete muscle tears. Rotation is the movement in which a part of the body rotates around its vertical (longitudinal) axis in the transverse plane. This movement is defined relative to the midline, where internal rotation involves rotating the segment towards to the midline, while external rotation involves moving it away from the midline. Examples include lateral or medial rotation of the thigh. Skeletal muscle: This type of muscle creates movement in the body. There are more than 600 skeletal muscles, and they makes up about 40 percent of a person’s body weight. When the nervous system signals the muscle to contract, groups of muscles work together to move the skeleton. These signals and movements are nearly involuntary, yet they do require conscious effort. However, humans do not need to concentrate on individual muscles when moving. As an individual ages, the joint tissues become less resilient to wear and tear and start to degenerate. This degeneration manifest as swelling, pain, and often-times, loss of mobility of joints. Changes occur in both joint soft tissues and the articulating bones, a condition called osteoarthritis. A more serious form of disease is called rheumatoid arthritis. The latter is an autoimmune disease wherein the body produces antibodies against joint tissues causing chronic inflammation resulting in severe joint damage, pain and immobility. For example, progesterone helps regulate the menstrual cycle and plays an important role in sustaining a pregnancy.Here's why our specialized quizzes will help you to master your weak spots and go into your anatomy exam with confidence. The heart also has an electrical system within. Electrical impulses within the heart help ensure that it beats with a consistent rhythm and proper rate. Fascicles or bundles (group of muscle fibres) of skeletal muscles can be arranged into four basic structural pattern, circular, parallel, convergent, and pennate. This difference in fascicular arrangement also accounts for the different shapes and functional capabilities of various skeletal muscles. The lateral head originates from the lateral surface of the lateral condyle and the lower part of the supracondylar line.
