The cardiac plexus is a nerve plexus of the autonomic nervous system, also known as the cardiac plexus. The deep portions of this network consist of sympathetic as well as parasympathetic nerve fibers and control the automatic action of the heart, which is beyond any external influence. Damage to the plexus can result in palpitations, … Cardiac Plexus: Structure, Function & Diseases
The subclavian artery becomes the axillary artery in the axillary region. This vessel supplies arterial blood to the entire arm area. Like all other arteries, the axillary artery can be affected by arteriosclerosis, which often results in infarction or necrosis as a late consequence. What is the axillary artery? The subclavian artery is also known … Axillary Artery: Structure, Function & Diseases
The internal carotid artery is also known as the internal carotid artery and supplies portions of the brain with arterial blood. Together with the external carotid artery, it arises from the common carotid artery. The internal carotid artery is particularly susceptible to arteriosclerosis as well as smaller aneurysms. What is the internal carotid artery? The … Internal Carotid Artery: Structure, Function & Diseases
The brachiocephalic truncus is a right vascular branch of the aorta and supplies portions of the brain in addition to the neck and right arm. Like any artery, the truncus carries blood rich in oxygen, nutrients, and messengers. Vascular diseases such as arteriosclerosis can affect the brachiocephalic truncus and require surgical intervention. What is the … Truncus Brachiocephalicus: Structure, Function & Diseases
The truncus pulmonalis is a short arterial vessel that forms a common trunk connecting the right ventricle and the right and left pulmonary arteries into which the truncus pulmonalis branches. At the entrance to the artery is the pulmonary valve, which closes during the relaxation phase of the ventricles (diastole) to prevent backflow of blood … Truncus Pulmonalis: Structure, Function & Diseases
The mediastinum corresponds to a tissue space of the thoracic cavity that houses all thoracic organs except the lungs. The organs are embedded within the mediastinum in connective tissue, which maintains their shape and performs supportive as well as protective functions. The mediastinum often becomes clinically relevant due to mediastinal tumors, which can displace the … Mediastinum: Structure, Function & Diseases
The aortic arch is effectively a 180-degree elbow of the body’s aorta, transferring the nearly vertical upward ascending aorta to the nearly vertical downward descending aorta. The aortic arch lies just outside the pericardium above the origin of the ascending aorta, which originates in the left ventricle. Three arteries or arterial trunks branch from the … Aortic Arch: Structure, Function & Diseases
The recurrent laryngeal nerve is a part of the X. Cranial Nerve. It is responsible for supplying the muscles of the larynx. Its very curved path in the brain is striking. What is the laryngeal recurrent nerve? The laryngeal recurrent nerve becomes the X. XII. Cranial Nerves. This is the vagus nerve. The laryngeal recurrent … Recurrent Laryngeal Nerve: Structure, Function & Diseases
The subclavian artery is called the subclavian artery. It is responsible for the complete blood supply to the arm. What is the subclavian artery? The subclavian artery is the subclavian artery. It refers to a paired blood vessel close to the trunk. The tasks of the artery primarily include arm blood supply. Thus, together with … Subclavian Artery: Structure, Function & Diseases
The internal thoracic artery is a smaller branch of the subclavian artery that supplies oxygenated blood to the chest cavity. The arterial vessel plays a role as a graft in procedures such as coronary bypass. Pathologic relevance has the artery like all other arteries, for example, in the context of arteriosclerosis. What is the internal … Internal Thoracic Artery: Structure, Function & Diseases
The scalenus anterior muscle, along with a total of three paired scalenus muscles, is part of the deep neck musculature. It originates from cervical vertebrae 3 to 6 (C3-C6) and pulls obliquely toward the 1st rib. The scalenus anterior muscle performs three main mechanical tasks; it is involved in lateral flexion and rotation of the … Anterior Scalenus Muscle: Structure, Function & Diseases
Diseases of the carotid artery Constriction (stenosis) or occlusion of the arteries supplying the brain If stenosis of an artery occurs due to arteriosclerosis, the blood supply to this vessel is reduced and thus the supply of oxygen decreases. If this constriction develops very slowly, i.e. chronically, a collateral circulation can develop via the other … Diseases of the carotid artery | Carotid artery anatomy and function
