Skeletal System

a joint cavity, the potential space bounded by the synovial membrane and articular cartilages of all synovial joints. Normally, the articular cavity contains only sufficient synovial fluid to lubricate the internal surfaces.

Because the skeletal system is about the skeleton.

The talus bone is crucial in ankle function because it forms part of the ankle joint, connecting the foot to the leg. It acts as a bridge between the lower leg and the foot, allowing for movement in multiple directions. Its unique shape and position play a significant role in weight-bearing and maintaining stability in the ankle joint.

Large bones, such as the femur and pelvic bones, contain bone marrow that is responsible for producing blood cells. The bone marrow contains stem cells that can differentiate into red blood cells, white blood cells, and platelets. Having large bones with ample space for bone marrow helps ensure a sufficient production of blood cells, which is essential for maintaining a healthy blood supply in the body.

The primary muscle responsible for extending the thigh is the quadriceps femoris, specifically the rectus femoris. To flex the knee, the primary muscles involved are the hamstrings, particularly the biceps femoris, semitendinosus, and semimembranosus. These muscle actions are important for movements like running and kicking.

It's actually the nerve bundle located in the elbow between the bones of your upper and lower arm. You can push it up against the bone and get the numbing pin-prick feeling from it all the way down your lower arm and fingers.

The three bones that fuse early in life are the sacrum, which is formed by the fusion of five sacral vertebrae, the ilium, and the ischium. Together, these bones form the pelvic girdle, which provides support and protection to the organs in the pelvic region.

There is no credible information available to suggest that Bizzy Bone from Bone Thugs-N-Harmony is dead.

The classification you are referring to is irregular bones. These bones have complex shapes and do not fit into other categories like long, short, or flat bones. Examples include vertebrae in the spine and certain bones in the face like the sphenoid and ethmoid bones.

never heard of a filenge, but a philange is a bone in your fingers or toes.

Osteoporosis is a disease that affects the bones by causing them to become weak and brittle, increasing the risk of fractures. Other diseases that can affect the bones include osteomalacia (softening of the bones due to vitamin D deficiency) and osteogenesis imperfecta (a genetic condition that causes brittle bones).

Bone forming cells are a type of specialized cells called osteoblasts which are responsible for producing new bone tissue. Osteoblasts play a crucial role in bone formation by synthesizing and secreting the proteins and minerals needed to build and repair bone.

The skeletal system consists of bones and related cartilage structures (such as in the ears, back, and knees), and the ligaments that connect the bones to other bones and to the muscles.

The main bones in the skeletal system are the skull and spinal column (vertebrae), the ribs, and the sternum, which protects the heart and lungs.

The other bones include the femurs (thigh bones) which are the biggest, the pelvis, the bones of the extremities (collarbone, scapula, radius, ulna, carpals, metacarpals, patella, tibia, fibula, tarsals, metatarsals, and phlanges) and the small bones of the inner ear.

The rib cage provides the most protection to the abdominal viscera. The ribs wrap around the viscera, such as the liver and spleen, helping to shield them from external trauma. The sternum at the front of the rib cage also contributes to protecting the organs in the abdominal cavity.

A fibrous joint, also known as a synarthrosis, is a type of joint found between immovable bones. These joints are held together by fibrous connective tissue, allowing for minimal to no movement between the bones. Examples of fibrous joints include sutures in the skull and syndesmoses in the lower leg.

No. A lot of people are confused by the term "hip replacement", since the term hip and the term pelvis often refer to the same structure. However, a "hip replacement" only involves replace of the hip joint, and very little of the pelvic structure other than that. Recall that the legs are connected to the pelvis via a ball-and-socket type joint. In a hip replacement, the worn out, natural "socket" (known as the acetabulum) is replaced with synthetic replacement, while topmost end of the thigh bone (femur) is removed to allow installation of the synthetic (usually titanium) "ball".

The tibia is connected to the fibula. They are both located on the leg below the knee.

The joint where bones meet and join solidly are called a fixed or immovable joint. These joints do not allow for movement and provide stability and support to the body. Examples include the joints between the bones of the skull.

The position that causes the most contact between the articular surfaces of the acetabulum and the head of the femur is hip extension with slight abduction and external rotation. This position maximizes the congruence between the two surfaces, allowing for more efficient load transmission and stability.

Humans and other vertebrates have an endoskeleton, which is an internal framework of bones that provides support, protection, and structure to the body. The endoskeleton allows for movement and growth as well as serving as a site for muscle attachment.

Technically, the kneecap itself cannot be sprained since it is a bone. However, the ligaments surrounding the knee cap can be sprained or injured. This condition is commonly referred to as a patellar sprain or patellar subluxation. If you suspect a sprain in the knee area, it's essential to seek medical advice for proper diagnosis and treatment.

Bones are hard, dense structures that provide support and protection for the body. Joints are where two or more bones come together and allow for movement. Connective tissue is a type of tissue that holds and connects different body structures together, including bones and joints.

Long bones contain compact bone tissue on the outer layer and spongy bone tissue on the inner layer. Compact bone provides strength and support, while spongy bone helps to reduce the bone's weight without compromising its strength.
