Is the Achilles tendon bone or cartilage?
The Achilles tendon is neither bone nor cartilage. It is, unsurprisingly, a tendon.
What is the tragus?
A tragus is the small flap of cartilage that sticks out in the front of the ear canal. It is often used as a site for piercing.
Is the funny bone a real bone?
The "funny bone" is the extension of the humerus bone (upper arm bone) into the elbow joint with the ulna (larger forearm bone). At the inside of the elbow, the ulnar nerve is located where the olecranon, or upper end of the ulna , meets the epicondyle, or lower end of the humerus. If the joint is struck, there is a tingling (a funny or odd sensation) and sometimes a temporary numbness in the lower arm, because the signals along the ulnar nerve are interrupted.This has little to do with the name of the upper arm bone being the humerus (humorous), which is the Latin word for "shoulder."
What part of the body is sometimes called the funny bone?
The humerus, which is the upper arm bone, is sometimes called the funny bone but, strictly speaking, this is not correct.In reality, the "funny bone" is not the bone at all, nor even the elbow, but the ulnar nerve at the end of the humerus where it meets the elbow. The ulnar nerve is the nerve that runs near the ulna bone of the lower arm. It is the nerve that sends messages to your brain about sensations in your fourth and fifth fingers. It's also one of the nerves that controls some movement of your hand.When this ulnar nerve is jolted or bumped against the end of the humerus, it creates the odd tingling sensation which has given rise to the term "funny bone".
What connect bones at a joint?
As with any structure, the human body is built upon a framework that is constructed to carry out a wide range of functions. The bones, ligaments, and tendons are each essential parts of the human framework, integrated into a mechanism, the skeleton, that is crucial to the movement, stability, protection, and growth of the entire body.There are approximately 206 bones in the human body. Bones generally act as connective tissue within the body. All bones are composed primarily of the mineral compound, calcium phosphate, which is a very hard substance, with a lesser amount of collagen (a protein). For this reason, bone is structured as a relatively brittle matrix, although the softer collagen cells lend some degree of elasticity when a bone sustains trauma. Not all bones possess the same characteristics, nor do all bones fulfill the same purpose within the skeleton.Because bone is a hard, white, and seemingly sterile object, it is perhaps difficult to regard the human skeleton as an organism. The bones, ligaments, and tendons are not only a coordinated frame upon which human muscles and organs are attached and contained, the skeleton and the rest of the body are an interconnected biological device.Ligaments are the skeletal components that connect bones to other bones to create a joint, a flexible structure that is capable of movement and of bearing both weight and external forces applied to it. Ligaments are made of collagen, formed into short, fibrous bands. All of the body ligaments are important to efficient physical movement. However, the ligaments that are of special significance are the anterior cruciate ligament (ACL), the connector between the femur and the tibia (lower leg bone) essential to knee function, and the ulnar cruciate ligament (UCL), an elbow structure essential to the success of any baseball pitcher.Tendons have a similar construction to that of ligaments: they are strong, fiber-like connectors. However, rather than connecting bone to bone, tendons connect muscle to bone, providing stability and a significant degree of resistance to external forces. Large tendons such as the Achilles tendon, which connects the gastroceus (calf muscle) and the calcaneus (heel bone), are able to withstand force due to the flexing qualities of the supple collagen that forms a large portion of the tendon structure. As with an ACL or UCL injury, a tear or rupture of the Achilles tendon is a debilitating occurrence.There are two types of bones: cortical bones and cancellous bones. Cortical bone has a denser, more compact structure than does the cancellous bone, and comprises the greater proportion of the skeleton mass. Most of the longer bones in the body are cortical, such as the femur (thigh bone). The long bones are hollow, and the center of the bone is filled with a substance known as yellow marrow. At the end of each long bone is an area known as the epiphysis, which is usually composed of cancellous bone cells; the marrow in this portion of the long bones is red marrow.Ligaments hold the bones together. They stretch from one bone over a joint to another bone.By ligaments.
