Which bones are formed by intramembranous ossification?
Long bones arms and legs
Bones of the pelvic girdle
Vertebrae
Flat bones of the skull
The Correct Answer is D
Intramembranous ossification is a process of bone formation in which bone tissue forms directly within mesenchymal (undifferentiated) connective tissue membranes. This process is responsible for the formation of the flat bones of the skull, including the frontal, parietal, occipital, and temporal bones.
Long bones of the arms and legs, bones of the pelvic girdle, and vertebrae are formed by endochondral ossification, a different process of bone formation in which bone tissue replaces hyaline cartilage.

Correct Answer is C
Explanation
The malleus, incus, and stapes are three small bones, collectively known as the ossicles, located in the middle ear. These bones work together to transmit sound waves from the eardrum to the inner ear, where they are converted into nerve impulses that are then sent to the brain. The malleus is atached to the eardrum, the incus is in between the malleus and the stapes, and the stapes is connected to the inner ear. Together, they form a chain that amplifies the sound waves and transmits them efficiently to the inner ear.
Correct Answer is C
Explanation
The urinary bladder and internal reproductive organs, including the uterus, ovaries, and testes, are in the pelvic cavity. The pelvic cavity is a bony structure formed by the pelvis and contains the terminal portions of the digestive tract, urinary tract, and reproductive tract. It is situated inferior to the abdominal cavity and is separated from it by the pelvic brim, which is a rim of bone formed by the iliac crests, sacrum, and pubic bones. The pelvic cavity is bounded by the pelvic bones and the pelvic diaphragm and is lined with the pelvic peritoneum.
