Women who have had radiation treatment to the chest, especially at a young age, are advised to have routine breast cancer screening. Yearly MRI screening may begin 8 years after treatment or by age 25 years, whichever is later. The benefits and risks of mammograms and MRIs for these women have not been studied.RI is used as a screening test for women who have one or more of the following: 1  Certain gene changes, such as in the BRCA1 or BRCA2 genes. 2  A family history (first degree relative, such as a mother, daughter or sister) with breast cancer.
Innervation of the Pectoralis Minor. In order for a muscle to contract and function, it must receive electrical impulses from the brain through a nerve or group of nerves, a process that is called innervation. The pectoralis minor muscle is innervated by the medial pectoral nerve. The medial pectoral nerve contains nerve fibers from the eighth cervical nerve (C8), which comes from the spine in the lower part of the neck, and the first thoracic nerve (T1), which comes from the spine in the upper part of the back. Lesson Summary. The pectoralis minor muscle is a
The muscles of the pelvic floor serve to support the organs both physically and functionally. There is also a more superficial layer thought to be more involved with sexual function. The nerve supply of the pelvic floor muscles is from the sacral nerves S2-S4 and travels from the sacrum through the pudendal nerve.Most of the nerve innervation is slow twitch which helps the muscles maintain a constant tone.FD is often associated with other conditions that cause chronic pelvic pain. Conditions like interstitial cystitis (IC), irritable bowel syndrome (IBS) and endometriosis, for example, stimulate the nervous system which sends signals to the pelvic floor to contract.
