"Pelycosauria" Natural Recordings by Native Speakers
Pelycosauria is a group of extinct synapsid vertebrates that lived during the Paleozoic and Mesozoic eras, around 300-250 million years ago. They were characterized by their skull structure, which resembled that of modern mammals. Pelycosauria includes well-known groups such as the pelycosaurs, therapsids, and mammals. They were an early experiment in the evolution of mammalian-like traits in terrestrial vertebrates.
Pelviectasis is a medical condition in which there is increased size or dilation of the pelvis, typically affecting the pelvis or the pelvic cavity. It can be a congenital condition, or it can occur as a result of other conditions or injuries.
A pelvimeter is a measuring instrument used to measure the shape and size of the pelvis and pelvis-related tissues, such as the distance between the ischial tuberosities or the diameter of the pelvic outlet. It is commonly used in medical and scientific research to aid in the diagnosis and treatment of various conditions, such as pelvic fractures, spinal deformities, and childbirth complications.
Pelvimetry is a medical term that refers to the examination or measurement of the pelvis, particularly the bony structure and soft tissues, to assess its size and shape. It is often performed in pregnant women to determine the likelihood of a smooth delivery, as a pelvis that is too small or misshapen may make a vaginal delivery difficult or impossible. Pelvimetry may be performed manually or using imaging technologies such as X-rays or ultrasound.
Pelvioscopy is a medical procedure that uses a pelvic scope to examine the pelvic organs, such as the uterus, fallopian tubes, and bladder, to diagnose or treat various gynecological conditions. The procedure involves inserting a flexible tube called a hysteroscope or laparoscope through the vagina or abdominal wall to visualize the pelvis and surrounding organs.
Pelviotomy is a surgical incision made through the pelvic wall, usually as a last resort during childbirth, to deliver a baby that is presenting in an abnormal position or is too large to pass through the birth canal.
The pelvis is the lower part of the torso, located between the abdomen and the legs. It is composed of four bones: two hip bones and two innominate bones. The pelvis acts as a foundation for the spine and supports the weight of the body. It also provides protection for the organs in the pelvic cavity, such as the bladder, uterus, and rectum. The pelvis is a common area for joints and muscles to be involved in low back pain, hip pain, and related conditions.
A pelycosaur is an extinct group of synapsid reptiles that lived during the Paleozoic and Early Mesozoic eras, around 300-250 million years ago. They were characterized by their mammal-like skulls, multiple small teeth, and amphibian-like bodies. Pelycosaurs were part of a larger group called synapsids, which also includes modern mammals. Some well-known pelycosaurs include Edaphosaurus, Dimetrodon, and Sphenacodon. They were likely carnivores or omnivores and played an important role in shaping the ecosystems of the time.

Pembrokeshire is a county in southwest Wales, UK. It is known for its stunning coastline, picturesque villages, and rich history and culture. The name "Pembrokeshire" comes from the medieval English Earl of Pembroke, who was granted lands in the area by the Normans. The county is often referred to as "Little England Beyond Wales" due to its unique cultural heritage, which has been influenced by its Celtic roots and English-speaking population.
Pembrolizumab is a humanized monoclonal antibody that belongs to the class of immunotherapy agents known as checkpoint inhibitors. It is used to treat various types of cancer, including melanoma, non-small cell lung cancer, classical Hodgkin lymphoma, and others. It works by blocking the action of a protein called PD-1, which is found on the surface of T-cells and helps to regulate the immune response. By blocking PD-1, pembrolizumab allows the immune system to more effectively recognize and attack cancer cells.
Pemetrexed is a type of chemotherapy medication used to treat certain types of cancer, such as non-small cell lung cancer and mesothelioma. It is often used in combination with other medications to treat advanced cancer that has not responded to other treatments. Pemetrexed works by inhibiting the growth of new blood vessels that feed tumors, thereby reducing the amount of oxygen and nutrients available to the tumor and ultimately leading to its death. It is typically administered intravenously and can cause side effects such as nausea, vomiting, and fatigue.
