Discussion 1 : No. 13 Hair & Nails – functions & structure
RESEARCH
Nails and hair not only help in regulating our body temperature but also work as a protective guard against injury on our toes and fingers. They are both made of a major Keratin protein, a protein that heals wounds, keeps our skin, nails, and hair in its healthiest state. Hair grows directly from follicles in the “dermis of the skin “ which covers the entire body except for a few areas, like your lips and palms of your hands. Hair provides insulation and helps our heads preserve heat. It also protects the skin from damage caused by UV light and the sun. As we know hair moves with breeze or when someone touches us, that’s due to a sensory function it has. Nails are made from layers of dead keratin, the protein in keratin hardens the nail which is how they protect our fingers. There are a few parts to the nail: The plate, the root, cuticles, and nail plate.
The root of the nail is found under the skins surface near or at the end of the nail.
The nail plate is the part that’s external to the skin, the most visible part of the nail.
The nail bed is the pinkish area under the skin; it has the pink color due to vessels in the dermis.
Nails are also an essential area used by health care professionals to quickly determine the oxygen levels and blood flow around limbs. You can also recognize certain health issues with someone’s nails such as fungal infections. Nails & hair are important areas of the human body.
CRITICAL THINKING
Personally, I always considered hair and nails to be an aesthetic. Something we just maintain and keep up with to look a certain way, not knowing they have other purposes. Of course, the hair on my head keeps my head warm especially experiencing winter when I lived in the northeast. However, the thought never came to me of how it protects me from UV/sunlight. Nails are art for me, painting, cutting, and growing them, something I change on the regular. Now understanding the actual purpose of our nails, I will work to keep them as healthy as they can be because they are essential.
DISSCUSSION 2 -Membranes-types, functions, and serosa types and locations
Research
Every part of the body has a protector or systems that work together to keep them not only safe and protected but always moving. The four tissue membranes are Mucous (Epithelial), Serous, Cutaneous and Synovial (Connective). These membranes cover most of the body, are internal passages and line against joints. According to louispressbook.pub (2022), explains the membranes as they relate to the body system that are in. The Mucous membrane is usually found in multiple systems such as the digestive, respiratory, reproductive and urinary, with the job of keeping mucous always secrete. The Cutaneous membrane main job is to cover the body surface or what is known as the skin. Synovial membranes produce fluid with the joints. Last, the Serous membrane is closest to the outside/exterior of the body cavities such as the pericardial, peritoneal and the pleural (Saladin, 2024).
Serous cavities are known to reduce friction that may lead to inflammation of other organs by protection with various sizes and complexity. Three of the most important serous cavities are Pleura, Pericardium, Tunica Vaginalis and Peritoneum. Pleura surrounds the lungs to help reduce friction between the lungs and body walls. Peritoneum mostly surrounds the abdominopelvic cavity with reducing friction in those areas. Last, Pericardium main goal is to protect the heart and its’ walls. One serous membrane many may not know is the Tunica Vaginalis that is in males and surrounds the testes in males. (biologydictionary.net, 2017).
Critical Thinking
When these membranes do not function correctly or at a lower standard then our bodies need it may lead to other issues within other organs. As someone who currently works in corrections, being able to move, run, bend is apart of my job and if I have an injury to a body part or cavity it may make it hard to do daily task. For example, the connective tissue/synovial membrane covers the lining of body parts such as the kidney and joints. In my current and future job, as a nurse, I would have to stay hydrated to keep my kidneys and joints in good condition to not cause any harm to any other organ systems or body parts. My future goal as a nurse, will help me be able to explain to patients how important it is to stay hydrated, keep a good exercise routine, eat healthy and get adequate rest to avoid having any future decline in health.
