Skeletal System

Intramembranous ossification produces flat bones of the skull, face, and clavicles. This process involves the direct ossification of mesenchymal cells without a cartilage precursor.

Capillary transport mechanisms refer to the movement of fluids through capillaries by processes such as diffusion, filtration, and osmosis. These mechanisms help to transport nutrients, gases, and waste products to and from cells in the body. The exchange of substances across capillaries is essential for maintaining proper tissue function.

short bones are mostly spongey bones and help hold shape and keep structure strong, flat bones usually protect or help with movementeg. the skull, sternum and scapula, long bones are also sponget bones that hold the shape of the body so that joints can function and move and irrregular bones are the miscelanious type of bone that varies in function, each one is different, eg. mandable and vertebrae.

The collarbones are also known as clavicles. They are long, slender bones that run horizontally across the front of the chest, connecting the shoulder blades to the sternum.

No, not all Canadians have an extra bone in their hands. The presence of an extra bone in the hand, called the os centrale, is considered a normal anatomical variation that can be found in some individuals, regardless of their nationality.

No, bones are not considered internal organs. They are a part of the skeletal system and provide structural support, protect organs, and aid in movement. Internal organs are typically soft tissues located inside the body cavities.

The appendicular skeleton has more bones than the axial skeleton. The axial skeleton includes the skull, spine, and rib cage, which have a total of 80 bones. In contrast, the appendicular skeleton includes the bones of the limbs, shoulders, and hips, totaling 126 bones.

the upper legs of a frog have less power than the back legs and they are different in lenth.

The spine of the scapula is located on the posterior aspect of the scapula, dividing it into the supraspinous fossa and infraspinous fossa. It is a prominent ridge that runs horizontally across the bone and serves as an attachment site for muscles that move the arm and shoulder.

A knee can be dislocated as a result of a sudden impact and force directly on the knee. For example: a direct hit on the knee from a fall. It can be dislocated as a result of an awkward running position as well. Dislocations can also occur from medical problems associated with disease.

Red bone marrow tissue is hematopoietic, meaning it is responsible for producing blood cells. Yellow bone marrow tissue, on the other hand, is primarily composed of fat cells and is not involved in the production of blood cells.

Hinge joints

An adult human body typically has 206 bones. This number can vary slightly from person to person due to the presence of small accessory bones or fusion of certain bones.

The person would not have lost their ability to detect sound (that is located in the inner ear). However, the ear mechanism would no longer work as it should and the person would not be able to hear properly as the sound would not be transmitted to the inner ear.

The hyoid bone is a unique bone in the human body because it is the only bone that doesn't directly articulate with any other bone. It is located in the neck and plays a role in supporting the tongue and larynx.

related to hip joint surgery mainly, for dimensional preciseness, corrosion resistance and compactness of any bone or demformity.

Severe chondrosis of the weight-bearing aspect of the medial femoral condyle refers to a significant degenerative condition affecting the cartilage on the inner part of the thigh bone where it meets the knee joint. This can result in pain, swelling, and limitations in movement, leading to reduced joint function and potentially requiring treatment such as physical therapy, medications, or in severe cases, surgery. It is important to follow the recommendations of a healthcare provider for proper management of this condition.

Neanderthals had short, heavy bodies with thick bones, small chins, and heavy brow ridges. They were an ancient human species that lived in Europe and parts of Asia until about 40,000 years ago. Neanderthals were well-adapted to cold environments and were skilled hunters.

periosteum : tough fibrous connective tissue membrane that covers the outside of the diaphysis. this protects the bone and serves as a point of attachment.

The inferior end of the femur articulates with the tibia and patella. The femur forms the knee joint with the tibia and the patella acts as a protector and provides leverage for the quadriceps muscles.

Yes, the MS hug is known to cause tight, constricting sensations around the torso which can feel like a band or belt squeezing around the ribs. It is often exacerbated by breathing and can be more pronounced on one side of the body. If you are experiencing these symptoms, it's essential to consult with a healthcare professional for proper evaluation and management.

No, synovial joints joints are freely movable joints. There are six types of synovial joints: gliding (arthrodial), hinge (ginglymus), pivot (trochoid), ellipsoid, saddle, and ball and socket.

The thoracic cavity is superior to the abdominopelvic cavity.

The bone that connects the mandible to the temporal bone is the temporomandibular joint (TMJ). It allows for movement of the jaw and is essential for functions like chewing and speaking. Issues with the TMJ can lead to conditions like temporomandibular joint disorder (TMD).

yes, the knee relfex felt when tapped just below the knee cap on the patellar tendon is a somatic reflex which is a contraction of skeletal muscles. the opposite would be autonomic relfexes which consist of contractions of smooth or cardiac muscle or secretion by glands.
