what is the difference between golgi tendon organs and muscle spindles?
604327
Golgi tendon organs are activated when the tendon attached to an active muscle is stretched. ... The result is a reduction in tension within the muscle and tendon. Thus, whereas spindles facilitate activation of the muscle, neural input from GTOs inhibits muscle activation.

The primary role of the Golgi apparatus is to modify the proteins and encase them into vesicles. From here they are transported to the various parts of the cell. Hence the three cell organelles are related in their functions of protein synthesis and transport.

Both are equally important cell organelles. The rough endoplasmic reticulum synthesizes proteins due to the presence of ribosomes and the golgi apparatus modifies these proteins to perform specific functions.

Muscle tissue that contracts without conscious control, having the form of thin layers or sheets made up of spindle-shaped, unstriated cells with single nuclei and found in the walls of the internal organs, such as the stomach, intestine, bladder, and blood vessels, excluding the heart.

Myofibrils are assembled of repeated structures called sarcomeres – the smallest functional unit of muscle fiber. Each sarcomere is formed of actin (called thin) and myosin (called thick) filaments arranged in a precise order and of protein complexes which support the filament structures.

Quick look: Golgi apparatus(or complex, or body, or 'the 'Golgi') is found in all plant and animal cells and is the term given to groups of flattened disc-like structures located close to the endoplasmic reticulum. ... The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum.

A muscle fascicle is a bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue. (There is also a nerve fascicle of axons.)

There are three specialized types of fibrous connective tissue. Ligaments connect bones to other bones, tendons (or sinew) connect muscle to bones and fasciae connect muscles to other muscles.

Ribosomes, the endoplasmic reticulum and the Golgi apparatus are related to each other through their involvement in protein synthesis and transport. ... The primary role of the Golgi apparatus is to modify the proteins and encase them into vesicles. From here they are transported to the various parts of the cell.

Mitotic Spindle Formation in Plants. Mitotic spindles are microtubule-based structures that separate chromosomes during mitosis. In most animals and fungal cells, spindle microtubules nucleate from centrosomes or spindle pole bodies.

When a muscle moves by flexing or extending, an aponeurosis acts like a spring to bear the extra pressure and tension. A tendon, on the other hand, moves a bone when a muscle contracts. Tendons allow the body to move and be flexible while aponeuroses allow the body to be strong and stable.

Both the smooth and rough endoplasmic reticulum help in the production and storage of proteins The main difference is that one contains ribosomes on it and the other does not. The rough endoplasmic reticulum (RER) has ribosomes on its surface. ... The Golgi apparatus tends to be on the other side of the RER.

As nouns the difference between myofibril and myofiber is that myofibril is (muscle) cylindrical organelles, found within muscle cells, that are the contractile unit of muscles while myofiber is muscle fiber.

Smooth muscle fibers are spindle-shaped (wide in the middle and tapered at both ends, somewhat like a football) and have a single nucleus; they range from about 30 to 200 μm (thousands of times shorter than skeletal muscle fibers), and they produce their own connective tissue, endomysium.

Remember that smooth muscle will present the features we've just seen, in either longitudinal or transverse cut. In dense connective tissue, the nuclei will usually be outside the fibers. Remember that smooth and skeletal muscle "fibers" are cells, while connective tissue "fibers" are cables of acellular collagen.

Histology. The biceps brachii is a skeletal muscle, and as such is an organ made mostly of skeletal muscle and connective tissues.
