What is the blood supply of arachnoid mater?
The middle meningeal artery supplies most of the blood for the dura mater, though the meningeal branches of the posterior and anterior ethmoidal artery also contribute.
What nerve supplies the serratus anterior muscle?
nerve supply: long thoracic, C5, C6, C7;
What are the functions of the two humors of the eye?
The aqueous humor moistens and supplies nutrients to the anterior and posterior chambers of the eye.The vitreous humor also moistens and supplies nutrients to the eye,in addition it serves as a shoke absorber (cushion) that privents the collapse of the eye.thy both helps in refraction of light rays.
What artery supplies blood to the right atrium and right ventricle?
The right side of the heart receives blood from the right coronary artery and the posterior descending artery.
What collective name is given to the posterior thigh muscles that the sciatic nerve supplies?
The medial compartment of the thigh includes the hamstring portion of the adductor magnus. This muscle is innervated by the sciatica.
What are the major branches of the coronary arteries and heart region served?
The left coronary artery branches into the anterior interventricular artery which supplies blood to the interventricular septum and anterior walls of both ventricles and the circumflex artery which supplies the left atrium and the posterior walls of the left ventricle. The right coronary artery branches into the right marginal artery which serves the myocardium of the lateral right side of the heart and the posterior interventricular artery which supplies the posterior ventricular walls.Reference: Marieb, Elain N. (2013).Human Anatomy & Physiology. 9th ed. United States: Pearsons Education, Inc.. p669-670.
What is the blood supply of arachnoid mater?
The middle meningeal artery supplies most of the blood for the dura mater, though the meningeal branches of the posterior and anterior ethmoidal artery also contribute.
What coronary artery most supplies to left ventricle?
The blood vessel which provides blood to most of the left ventricle is the Left Anterior Descending artery, a branch of the Left Main Coronary Artery. The Circumflex artery, also a branch of the Left Main, also supplies blood to the posterior left ventricle.
Artery that supplies blood to the heart wall?
The two main vessels that arise from the Sinus of Valsalva, located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle. Finally, the posterior descending artery can arise from either the right or left coronary artery. If the posterior descending artery arises from the right coronary artery, the heart is termed right heart dominant, which is seen in approximately 70% of individuals. If the posterior descending artery arises from the left circumflex artery, it is termed left heart dominance. It is also possible for the posterior descending artery to arise from both the right and left coronary artery. In this configuration, the heart is considered co-dominant. The posterior descending artery mainly supplies the inferior wall of the left ventricle and the inferior portion of the septal wall.
Nerve supply of the tibialis anterior muscle?
deep peroneal nerve supplies the tibialis anterior muscle
What is the name of the artery that supplies blood to your leg?
The posterior tibial artery carries blood to the posterior of the leg. This artery also branches off into the fibular artery, which supplies blood to the lateral compartment of the leg.
What name is given to the posterior thigh muscles that the sciatic nerve supplies?
Hamstrings
Which artery supplies the soleus muscle?
Posterior tibial artery and peroneal artery.
What major artery supplies the heart itself blood?
The coronary arteries. These leave the aorta and branch out over the heart. Blood only flows though these vessels during diastole because during systole they are blocked off by the aortic valve. The two main vessels that arise from the Sinus of Valsalva, located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle. Finally, the posterior descending artery can arise from either the right or left coronary artery. If the posterior descending artery arises from the right coronary artery, the heart is termed right heart dominant, which is seen in approximately 70% of individuals. If the posterior descending artery arises from the left circumflex artery, it is termed left heart dominance. It is also possible for the posterior descending artery to arise from both the right and left coronary artery. In this configuration, the heart is considered co-dominant. The posterior descending artery mainly supplies the inferior wall of the left ventricle and the inferior portion of the septal wall.
What is the Most common variation of the circle of Willis?
The proximal part of the posterior cerebral artery is narrow and its ipsilateral posterior communicating artery is large, so the internal carotid artery supplies the posterior cerebrum.
What circulatory system supplies the heart with blood?
Through it's own network of arteries in the heart itself. These are the arteries that are disrupted during a heart attack, and they are also bypassed during a bypass surgery with veins from the legs.
What blood vessel supplies blood to the skin covering the anterior thigh?
The femoral artery
