Skeletal muscle tissue

In the leg, there are muscles called adductors whose role is to adduct pull together the legs. Cardiac muscle tissue cannot be controlled consciously, so it is an involuntary muscle. Similarly, some insects vibrate their wings for a while before flight, heating the muscles to the temperature at which they work best.

Between the myofibrils are the mitochondria. Osteoblasts deposit new lamellae of bone matrix on the walls of these tunnels resulting in the formation of a new Haversian system within the matrix of compact bone.

Most features of bone but not the canaliculi, which are only visible on ground bone may be found on these slides, which include not only bone but also bone marrow on the inside and often periosteum and muscle on the outside.

Cartilage is relatively stiff and incompressible. Contracting muscles produce vibration and sound. This epiphyseal plate is the site of bone elongation, with new cartilage forming on the epiphyseal side of the plate while endochondral ossification extends the diaphysis on the other side of the plate.

Most mature bones are more-or-less hollow. The elastic cartilage slide is stained for elastin the fine purple strands within the matrix ; otherwise it would look just like hyaline cartilage. For example, the biceps brachii muscle flexes the arm at the elbow.

Skeletal muscles[ edit ] Connective tissue is present in all muscles as fascia. The femur is the largest bone in the body and the only bone of the thigh femoral region. The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ.

The process repeats indefinitely, with fragments of the lamellae from older Haversian systems being left behind as interstitial lamellae when new systems are formed.

You can learn about musculoskeletal health problems in our section devoted to diseases and conditions. Collagen in the matrix is left intact by the decalcification process, so the bone matrix appears eosinophilic i. Type I, slow oxidative, slow twitchor "red" muscle is dense with capillaries and is rich in mitochondria and myoglobingiving the muscle tissue its characteristic red color.

A balance between osteoclast and osteoblast activity is necessary for a stable calcium level in blood. That is, active osteoblasts that become enclosed in bone may adopt the resting osteocyte form, while osteocytes which are released from their bony matrix by osteoclast activity may become active osteoblasts.

During endochondral ossification, osteoblasts and blood vessels must actually invade the cartilage precursor. Certain conditions or disorders, such as myoclonus, can affect the normal contraction of muscles. The 3 types of muscle tissue are cardiac, smooth, and skeletal.

Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs, except the heart, appear spindle.

Clinical relevance of skeletal tissue histology. Initial treatment for broken bones usually involves basic mechanical considerations, stabilizing the structure to prevent further injury. TYPES OF MUSCLE TISSUE.

Muscle occurs in three distinct types.

Skeletal muscle uses and demands nutrients and oxygen that are supplied by blood vessels that enter the muscle along the connective tissue partitions and.
