Bronchitis Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs. Symptoms include coughing up mucus, wheezing, shortness of breath, and chest discomfort. Bronchitis is divided into two types: acute and chronic. Acute bronchitis is also known as a chest cold. Acute bronchitis usually has a cough that lasts around three weeks. In more than 90% of cases the cause is a viral infection. These viruses may be spread through the air when people cough or by direct contact.

- Hiccups are repetitive, uncontrollable contractions of the diaphragm muscle. Your diaphragm is the muscle just below your lungs. It marks the boundary between your chest and abdomen. The diaphragm regulates breathing. When your diaphragm contracts, your lungs take in oxygen.When your diaphragm relaxes, your lungs release carbon dioxide. The diaphragm contracting out of rhythm causes hiccups. Each spasm of the diaphragm makes the larynx and vocal cords close suddenly. This results in a sudden rush of air into the lungs.Your body reacts with a gasp or chirp, creating the sound characteristic of hiccups.he diaphragm regulates breathing. When your diaphragm contracts, your lungs take in oxygen. When your diaphragm relaxes, your lungs release carbon dioxide. The diaphragm contracting out of rhythm causes hiccups.

- The diaphragm, a smooth skeletal muscle used to control respiration, is nominally an involuntary muscle, although limited voluntary control can be achieved. The diaphragm operates using the phrenic and lower intercostal nerves to communicate with the brainstem. Keep Learning.

- Contractions of cardiac muscles move blood throughout the veins and arteries of the circulatory system. Involuntary muscles in the eye's iris to expand and contract in response to light. A beating heart is one of the best examples of an involuntary muscle. Contractions of cardiac muscles push blood through the four chambers of the human heart.

What is Muscle Contraction? Smooth and cardiac muscles are involuntary muscles, so they do not need to be consciously stimulated for contractions to take place. Instead, a muscle contraction of smooth or cardiac muscle is initiated within the organ itself.

Bronchi and Bronchioles The main function of the bronchi and bronchioles is to carry air from the trachea into the lungs. Smooth muscle tissue in their walls helps to regulate airflow into the lungs. When greater volumes of air are required by the body, such as during exercise, the smooth muscle relaxes to dilate the bronchi and bronchioles.

Can you feel a broncospasm and what does it feel like? Bronchospasm is a chief characteristic of asthma and bronchitis. Description. Bronchospasm is a temporary narrowing of the bronchi (airways into the lungs) caused by contraction of the muscles in the lung walls, by inflammation of the lung lining, or by a combination of both.This contraction and relaxation is controlled by the autonomic nervous system.ontraction may also be caused by the release of substances during an allergic reaction. The most common cause of bronchospasm is asthma, though other causes include respiratory infection, chronic lung disease (including emphysema and chronic bronchitis), anaphylactic shock, or an allergic reaction to chemicals.

Hiccups Hiccups are caused by involuntary contractions of your diaphragm — the muscle that separates your chest from your abdomen and plays an important role in breathing. This involuntary contraction causes your vocal cords to close very briefly, which produces the characteristic sound of a hiccup.

Causes of Bronchodilation Causes of Bronchodilation. Bronchodilation is the process by which the bronchi (tubes in the lungs made of connective tissue and muscle) are dilated, or opened. There are circumstances and conditions that cause the bronchi of the lungs to become narrow, or constrict, making it difficult to breathe. There are endogenous (inside the body) and exogenous (originating outside the body) factors that can affect bronchodilation.

What are Involuntary Muscles? Both smooth muscle and cardiac muscle can be classified as involuntary muscles. Smooth muscle is comprised of spindle-shaped cells that have no striations and is found in numerous locations throughout the human body. Cardiac muscle is striated rather than smooth, and is found only within the walls of the heart.

What causes bronchoconstriction? Physiology [edit]. 1. Bronchoconstriction is due to an activation of parasympathetic nervous system. Postganglionic parasympathetic fibers will release acetylcholine (ACh) next to the Reissessen muscle, a smooth muscle layer surrounding the bronchi.These smooth muscle cells have M3 type muscarinic receptors on their membrane.ostganglionic parasympathetic fibers will release acetylcholine (ACh) next to the Reissessen muscle, a smooth muscle layer surrounding the bronchi.

Muscle contraction The contraction produced can be described as a twitch, summation, or tetanus, depending on the frequency of action potentials. In skeletal muscles, muscle tension is at its greatest when the muscle is stretched to an intermediate length as described by the length-tension relationship. Smooth and cardiac muscle contractions are myogenic and can be modulated by the autonomic nervous system.

Hiccups Patient Comments Read 18 Comments Share Your Story. Hiccups are sudden, involuntary contractions of the diaphragm muscle. As the muscle contracts repeatedly, the opening between the vocal cords snaps shut to check the inflow of air and makes the hiccup sound. Irritation of the nerves that extend from the neck to the chest can cause hiccups. Although associated with a variety of ailments (some can be serious such as pneumonia or when harmful substances build up in the blood for example from kidney failure), hiccups are not serious and have no clear reason for occurring.
