What type of tissue make up the diaphragm?
Answers: Muscles
There are three different types of muscle tissue. These include the skeletal muscles which are under voluntary control and are made of striated muscle tissue, the visceral muscles which are under involuntary control and are made of smooth muscle tissue, and cardiac muscle tissue which is found individual in the heart. Cardiac muscle tissue has properties contained by common with respectively of the other two types. An interesting exception to the visceral muscles being under involuntary control is the diaphragm, which controls breathing. This muscle is in general under involuntary control (we don’t usually have to deliberate about breathing), but a person can exert a set amount of voluntary control also (for example, purposely holding one’s breath or breathing quickly or deeply).
Muscle cells contain filament of two kinds of proteins, actin and myosin, which slide past respectively other as the muscle contracts. After a muscle contracts, ATP (produced in the muscle cells’ mitochondria) is needed to relax the muscle and return the actin and myosin filaments to their majority positions. When a person (or other animal) dies and the mitochondria are no longer producing ATP, the muscles cannot relax. This stiffening of the muscles is called rigor mortis. Muscle contraction is initiated when an electrical caprice from a nerve cell reaches its associated muscle cell(s), cause positively- and negatively-charged ions to switch places all along the muscle cell (fiber). Movement of Ca++ ions in/out of the muscle cell (fiber) is important within both contraction and relaxation of the muscle, so if a person doesn’t ingest enough calcium, some could be taken out of the bones to supply the muscles next to what they need to contract and relax. Any given muscle fiber reacts surrounded by an “all or none” response — it is either relaxed or contracted, and the variability within contraction of the overall muscle is based on the number of fibers which contract.
It is important to remember that muscles can individual pull or contract, not push. Thus, many muscles come within sets of antagonists that do opposite jobs. For example, the muscle on the “top” of your arm bends the arm at the elbow while the muscle “under” your arm straightens the arm.
