  9. Can you name the five regions of the vertebral column and the number of vertebrae in each region?

  10. What is the process by which bone tissue is formed, and what are the two types of cells involved in this process?

  11. What term describes the type of joint found in the skull, characterized by immovable connections?

  12. Identify the bone that is commonly known as the “collarbone.”
  13. What is the name of the condition characterized by a decrease in bone density, leading to increased fragility of the bones?

  14. The radius and ulna are two major bones found in which part of the human body?

  15. What type of bone cell is primarily responsible for the resorption or breakdown of bone tissue?

  16. Can you name the largest joint in the human body?

  17. How many pairs of ribs does a typical human have, and how are they categorized?

  18. What is the anatomical term for the growth plate found in long bones?

  19. Which type of synovial joint allows for movement in all directions, and can you give an example of where it is found in the body?

  20. How does the structure known as the “vertebral foramen” contribute to the nervous system?

  21. What is the primary mineral stored in bones, contributing significantly to their hardness and strength?

  22. Which bone is considered the smallest in the human body, and where is it located?

  23. Which bone is known to be the only bone in the human body that is not directly attached to other bones, thus being termed “floating”?

  31. How does the skeletal system contribute to the regulation of pH in the body?

  32. What is the name given to the type of bone found at the ends of long bones, which aids in the absorption of shock and reduction of friction in joint movements?

  33. What specific type of connective tissue attaches muscles to bones?

  34. The condition in which the arch of the foot collapses, leading to the entire sole of the foot coming into complete or near-complete contact with the ground is called what?

Answers

  1. The femur, located in the thigh.

  2. The patella, also known as the kneecap, acts primarily as a protection for the knee joint and aids in the extension of the knee by the quadriceps.

  3. The adult human body typically has 206 bones, while a newborn may have approximately 270 bones; some bones fuse together as one grows.

  4. Twenty-two bones comprise the adult human skull.

  5. The malleus, incus, and stapes, collectively referred to as the ossicles.

  6. Cortical bone, also known as compact bone, is dense and forms the outer layer of bone, providing strength and support. Trabecular bone, or spongy bone, is found inside bones and has a porous structure that helps to absorb shock.

  7. Kyphosis, which affects the thoracic (upper) spine.

  8. The hyoid bone is the only bone in the human body that does not articulate (form a joint) with any other bone, significant for its role in speech and swallowing.

  9. The vertebral column is divided into five regions: cervical (7 vertebrae), thoracic (12 vertebrae), lumbar (5 vertebrae), sacral (5 fused vertebrae in adults, forming the sacrum), and coccygeal (4 fused vertebrae forming the coccyx or tailbone).

  10. The process is called ossification. The two types of cells involved are osteoblasts, which build up bone, and osteoclasts, which break down bone tissue.

  11. Sutures.

  12. The clavicle.

  13. Osteoporosis.

  14. The forearm.

  15. Osteoclasts.

  16. The knee joint.

  17. Twelve pairs of ribs, categorized into true ribs (first seven pairs attached directly to the sternum), false ribs (next three pairs, indirectly attached to the sternum or not at all), and floating ribs (last two pairs, not attached to the sternum).

  18. The epiphyseal plate.

  19. The ball and socket joint; examples include the shoulder and hip joints.

  20. The vertebral foramen is the canal through which the spinal cord passes, providing protection and support to this crucial part of the nervous system.

  21. Calcium.

  22. The stapes, located in the middle ear.

  23. The hyoid bone.

  24. The tibia.

  25. Eight carpal bones.

  26. The cervical section.

  27. The primary function of the axial skeleton is to provide support and protection for the brain, spinal cord, and vital organs, and it forms the central framework of the body.

  28. Hematopoiesis.

  29. The coccyx.

  30. The hinge joint.

  31. The skeletal system helps regulate pH by storing or releasing alkaline salts from bone, which can buffer blood against excessive pH changes.

  32. Articular cartilage.

  33. Tendons.

  34. Flatfoot or pes planus.
