Skeletal System

There are four main types of bones in the human body: long bones (e.g. femur, humerus), short bones (e.g. carpals, tarsals), flat bones (e.g. skull, ribs), and irregular bones (e.g. vertebrae, hip bones). Each type of bone has a specific shape and function in the body.

My right leg from the knee down feels tight and a feeling of restlessness. At time feels tight lke it is swollen but it is not. When I elevate it there is some relief. There has been no change in skin colouring. This is only experienced on my right leg not my left....I have two little fluid lumps on my inside arch. They are not painful. Please advise.

The protective mucous layer covering the bone surface is called periosteum. It is a dense layer of connective tissue that helps in bone repair and growth by providing a blood supply and anchoring the tendons and ligaments to the bone.

The proximal and distal phalanges only meet in the first digits (the thumbs and the big tues). This joint is the first interphalangeal joint.

Well, to answer the question directly, skin protects the ribcage. If the question reversed (what organs does the ribcage protect?), then my answer would be that the ribcage primarily protects the heart and lungs, although it does protect the spleen and, to a lesser extent, the liver and stomach.

No, the spine is not considered a long bone. Long bones, like those found in the arms and legs, have a cylindrical shape with growth plates at each end, while the spine is made up of individual vertebrae stacked on top of each other to form the backbone.

Stretch receptors in the bladder wall are activated when the bladder fills with urine or liquid. These receptors signal the brain to indicate the fullness of the bladder, triggering the urge to urinate.

The real name for the backbone is the spine, which is made up of a series of interconnected bones called vertebrae. The spine serves as a protective structure for the spinal cord and provides support for the upper body.

The heart is the part of the human body that has no bone, is full of veins, pumps blood throughout the body, and is involved in the physical response during sexual activity.

Yes, the quadriceps muscle is a group of four muscles located in the front of the thigh that plays a major role in knee extension. The quadriceps muscles connect to the kneecap and help stabilize and provide movement for the knee joint.

It is not advisable to walk on a treadmill with a broken rib as it can cause further discomfort and delay the healing process. It is best to rest and allow your rib to heal properly before engaging in any physical activity.

Diploe does not belong because it refers to the inner layer of flat bones like the skull that contains both spongy and compact bone. Spongy bone, red marrow, hematopoiesis, and yellow marrow are all related to bone structure and function.

B/c our bodies respond to what we ask of them. If we use them, they grow strong enough to be used. If we only slouch around in sofas, they'll respond by only being strong enough to be couch potatoes.

A broken bone can be seen through symptoms like swelling, bruising, deformity, or inability to move the affected body part normally. X-rays are usually necessary to confirm the diagnosis of a broken bone.

Actually there are 3 bones in the arm. The Humerus, which is where your Biceps are, the Radius, which is the bone connected to your thumb, and the Ulna, which is connected to your pinky finger. I always remember Ulna, because it sounds like an old lady's name, and old lady's always have their little tea cups and stick their pinky in the air when they sip! My science teacher taught me that.

The term for a large rounded articulating knob is "lunate."

If you had no bones, the organ system most affected would be the musculoskeletal system. Without bones, you would have no structure or support for your muscles to attach to, making movement and posture difficult. Additionally, your bones play a role in protecting vital organs and producing blood cells.

The human hand has more bones than the human foot. The hand has 27 bones, while the foot has 26 bones.

Signs and symptoms that someone needs first aid vary greatly. If someone has fallen, pain somewhere in the body can mean that first aid is needed. If someone is laying on the floor and not responding, is bleeding from a cut, choking on food, or a host of other things, it is a sign that first aid is needed. First aid can be anything from putting a band aid on a minor cut to giving CPR. In order to know what first aid is needed for what sign or symptom, first aid training is available.

It is common for individuals to have asymmetries in their skull shape that result in bumps or irregularities. If the bump is not causing any pain or symptoms, it is likely not a cause for concern. However, if you notice any changes in size, shape, or if it causes discomfort, it is advisable to consult with a healthcare provider for a proper evaluation.

The Scapula articulates with the humerus and clavicle to make the shoulder socket.

Calcium is the nutrient that helps keep your bones and teeth strong. It is important for bone formation, density, and strength. Dairy products, leafy green vegetables, and fortified foods are good sources of calcium.

Bones grow primarily at the ends, or growth plates, where new bone tissue is formed. This process is known as endochondral ossification. Growth in length occurs through a combination of cell division and mineralization within the growth plates.

Yes, it is normal for one rib to be slightly bigger than the other due to natural anatomical variations. However, if you notice a significant difference in size or experience pain or discomfort, it is recommended to consult a healthcare professional for further evaluation.

No, the stomach does not contain cartilage. The stomach is a muscular organ that contains layers of smooth muscle tissue and specialized cells that secrete digestive enzymes and acids to aid in food digestion. Cartilage is found in joints and areas where flexibility and support are needed.
