In the periosteum it surrounds the bone surface wherever it is not covered by articular cartilage, it is a sheath of dense irregular connective tissue containing osteoblasts, it functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serves as an attachment point for ligaments and tendons. 4- Which kind of bone marrow is in spongy bone tissue? Red bone marrow is the type of marrow found in spongy bone tissue. 5- Which ossification method would form a femur? Endochondrial ossification would form the femur.
Dermis is mainly connective tissue, is deep to the epidermis, and is vascular * The skin contains collagen (for strength) and elastic (for stretch) fibers. * The skin is thicker on the posterior than the anterior parts of the body; thicker on lateral parts of limbs than medial parts. —Subcutaneous layer (or hypodermis) is deep to dermis, but is not part of skin. It is mainly adipose tissue B. Layers of epidermis (from deepest to superficial) 1. Stratum Basale (= base) a. has stem cells that continuously divide by mitosis
1. Understand anatomy and physiology in relation to moving and positioning individuals 1.1 Outline the anatomy and physiology of the human body in relation to the importance of correct moving and positioning of individuals: Muscles: - It is important to move an individual’s limbs safely, avoiding pushing or pulling roughly, as this may cause tendons and muscles to contract too strongly, overstretching or tearing them and causing strains. Joints: - Sprains may also occur in the ligaments, when a joint is forced either out of its normal movement range. There are three different types of joint: - Fixed joints, which have no movement (e.g. in the skull) - Cartilaginous joints, which have small amounts of movement (e.g.
The inguinal ligament support the area between the abdomen and the thigh (Inguinal Ligament, n.d.). It is like a giant rubber band that prevents the intestines from distending into the groin. Continuing north, we can see that we are going to merge into a larger vein, the inferior vena cava. As you can see, I am not the only one making my way through here. Blood from the left side of the body is also making its way to the lower lobe of the lung from this route.
The ball and socket joints are the most mobile type of joint in your body. Other joints such as those between the vertebrae in your spine, which are connected to each other by pads of cartilage, can only move a small amount. Most of your joints are ‘synovial joints’; they are moveable joints containing a lubricating liquid called synovial fluid. Synovial joints are predominant in your limbs where mobility is important. Ligaments help provide their stability and muscles contract to produce movement.
It is a triangular shaped bone and acts like a shield to protect the knee structure behind. The existence of subcutaneous bursa makes the patella totally separated from the skin. The main body of patella is mostly covered by a thick layer of articular cartilage and surrounded by four quadriceps muscles. Those quadriceps tendons insert to the patella in order to provide the biomechanical function. It plays the most important role in the extensor mechanism of the knee joint (3).
Unit 4222-229 Undertake agreed pressure area care (HSC2024) Karen Yardley Outcome 1 understand the anatomy and physiology of the skin in relation to pressure area care 1.1 describe the anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores. The skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of the skin is around 3000sq inches depending on age, height and body size. As well as the nails, hair, sweat glands and the sebaceous glands, the skin forms the integumentary system. Besides oroviding protection to the body, the skin also helps regulate body temperature, helps your immune system, provides sensations of touch, heat, cold and pain throught the sensory nerve endings.
There are two types of cartilage (a firm but flexible type of connective tissue) in the knee: hyaline and fibrous cartilage. The knee’s articular surface is covered in hyaline cartilage (also known as articular cartilage). The hyaline cartilage in the knee covers the inferior end of the femur, the top of the tibia and the posterior the patella. The hyaline cartilage is covered in viscous fluid called synovial fluid, which allows the surfaces of the bones to
Hyaline cartilage thinly covers the articulating ends of bones, connects the ribs to the sternum, and supports the nose, the trachea, and part of the larynx. It is covered by a membranous perichondrium, except where it coats the ends of bones, and tends to calcify in advanced age PERIOSTEUM- a thick, fibrous vascular membrane covering the bones, except at their extremities. It consists of an outer layer of collagenous tissue containing a few fat cells and an inner layer of fine elastic fibers. Periosteum is permeated with the nerves and blood vessels that innervate and nourish underlying bone. The membrane is thick and markedly vascular over young bones but thinner and less vascular in later life.
Head Injury Overview Traumatic head injuries are a major cause of death, and disability but it might be best to refer to the damage done as traumatic brain injury. The purpose of the head, including the skull and face, is to protect the brain against injury. In addition to the bony protection, the brain is covered in tough fibrous layers called meninges and bathed in fluid that may provide a little shock absorption. When an injury occurs, loss of brain function can occur even without visible damage to the head. Force applied to the head may cause the brain to be directly injured or shaken, bouncing against the inner wall of the skull.
