Skeletal System

facet (or zygopophysial) ligaments surround the posterior aspect of the facet (or zygopophysial) joints of the spine. they function to strengthen the joint and give extra support. facet joints of the spine are also known as posterior intevertebral joints.

Fetal skull moulding is the process by which a newborn's skull bones shift and overlap during passage through the birth canal, allowing for easier delivery. This molding is a normal part of the birthing process and typically resolves within a few days after birth as the skull bones return to their normal position.

These extensions are known as alveolar processes, and they support and anchor the teeth within the mouth. The alveolar processes of the mandible and maxilla are the bony ridges that contain the tooth sockets (alveoli). The shape and size of these processes vary depending on the number and type of teeth present in the mouth.

It is located on temporal side of the skull and it is where sounds enters the human ear leading to the tympanic membrane. It is sometimes referred to as the extermal auditory canal.

Osteoblasts are the cells responsible for building bone tissue. They produce the matrix that eventually becomes mineralized bone.

The needle-like threads of spongy bone are called trabeculae. These structures help provide support and strength to the bone while also allowing for the passage of blood vessels and bone marrow. Trabeculae help distribute forces and maintain the structural integrity of the bone.

The ethmoid bone in the skull is known for being full of small holes called foramina. These holes allow for the passage of nerves and blood vessels that supply various structures in the head.

The axon terminals of a nerve cell and the sarcolemma of a skeletal muscle cell join at the neuromuscular junction. This is where the nerve impulse triggers the release of neurotransmitters, such as acetylcholine, which initiate muscle contraction by binding to receptors on the sarcolemma.

In America there is a pie called american pie

Joints may be synovial (with a cavity) or fibrous. Synovial joints are filled with synovial fluid. Fibrous joints lack this. Fibrous joints are found in between the vertebrae.

Cartilage in is both joints. This can be hylaine or fibrocartilage. Both regenerate.

The synovial fluid is rather slippery and allows easy movement in those joints. If this joint is suddenly and rapidly pulled, the fluid doesn't fill quickly and a "snapping" sound is heard.

The medical term for partial dislocation of a joint is "subluxation." It refers to a partial or incomplete dislocation where the joint surfaces are partially separated but not completely out of place. Symptoms can include pain, swelling, and limited range of motion at the joint. Treatment may involve rest, physical therapy, or in some cases, joint stabilization.

No, it is not possible for a person to have two tailbones. The tailbone, also known as the coccyx, is a single, small bone located at the bottom of the spine in humans. If your son is experiencing unusual symptoms in his tailbone area, it is best to consult a healthcare professional for an accurate diagnosis.

The fontanels of a baby skull are made of connective tissue. They are soft spots between the skull bones that allow for some flexibility during birth and rapid brain growth in the first year of life. Over time, these fontanels close as the bones of the skull fuse together.

No, the lacrimal bone is a small, fragile bone that contributes to the bony orbit of the eye, while the lacrimal fossa is a depression on the medial wall of the orbit that houses the lacrimal sac, which is responsible for draining tears from the eyes.

The man's wrist is a component of the official man's hand. It is 18.23 cm in diameter. The wrist is also cast in platinum and held in the Louvre.

parietal pleura: outer fold of the pleura lying closest to the ribs

The strongest bones in the human body are typically long bones, such as the femur and tibia in the legs. These bones are designed to support the body's weight and withstand forces during activities like walking and running. Additionally, bones in the skull, like the mandible and maxilla, are also considered strong due to their protective function for the brain.

The last bone to ossify in the human skeleton is typically the clavicle or collarbone, which doesn't fully fuse and ossify until early adulthood, around the age of 25. This delayed ossification allows for more flexibility during childbirth.

The fibrocartilaginous callus forms during fracture healing to stabilize and bridge the gap between bone ends. It consists of fibrous tissue and cartilage, providing structural support and promoting new bone formation at the fracture site. Over time, the fibrocartilaginous callus remodels into mature bone tissue.

The nutrient foramen is typically found on the diaphysis of long bones, towards the middle of the shaft. It serves as an entry and exit point for blood vessels that supply nutrients to the bone tissue.

The tough outer covering of bone is called the periosteum. It is a dense connective tissue that protects the bone and plays a role in bone growth and repair.

The lower jaw bone is the only movable bone

The interconnecting tiny arches of bone tissue found in spongy bone are called trabeculae. Trabeculae provide structural support and help distribute stress within the bone.

Human bones do not naturally turn green. If bones appear green, it may be due to factors such as algae growth due to environmental conditions or discoloration from chemicals or dyes. It is important to consult a medical professional if you notice any unusual changes in bone color.
