Which is not part of your appendicular skeleton?
Ulna.
Ethmoid bone.
Ilium.
Patella.
The Correct Answer is B
The ethmoid bone is a part of the axial skeleton, not the appendicular skeleton.
The axial skeleton consists of the bones of the skull, vertebral column, ribs, and sternum.
Choice A is incorrect because the ulna is a part of the upper limb, which is supported by the pectoral girdle.
Choice C is incorrect because the ilium is a part of the hip bone, which forms the pelvic girdle.
Choice D is incorrect because the patella is a part of the lower limb, which is supported by the pelvic girdle.

Correct Answer is D
Explanation
Bone marrow is the soft, spongy tissue that fills the medullary cavity of long bones.
Bone marrow contains hematopoietic stem cells that produce blood cells, as well as fat cells and other supportive cells.
Choice A is incorrect because spongy bone is not the tissue that fills the medullary cavity, but the type of bone tissue that surrounds it.
Spongy bone has a porous structure that provides strength and flexibility to the bone.
Choice B is incorrect because compact bone is not the tissue that fills the medullary cavity, but the type of bone tissue that forms the outer wall of the diaphysis.
Compact bone has a dense and hard structure that provides protection and support to the bone.
Choice C is incorrect because none of these is not a valid answer.
The medullary cavity of long bones does contain a specific type of tissue, which is bone marrow.
Correct Answer is ["Foramen transversarium"]
Explanation
The foramen transversarium is a canal that is found in the transverse process of the cervical vertebrae, C1 through C7.
It is an opening in the bone that allows the passage of the vertebral artery, vertebral vein, and sympathetic nerves.
The vertebral artery passes through the foramen transversarium in C1-C6 vertebrae, while the vertebral vein passes through the foramen in C1-C7 vertebrae.
The sympathetic nerves pass through the foramen in C1-C6 vertebrae as well.
Injuries to the foramen transversarium can cause damage to the vertebral artery and vein, leading to a variety of symptoms, including dizziness, headaches, and visual disturbances.
