Final answer:
The sentence 1) the head, together with all its parts contains the brain and sensory organs is the correct finish as it reflects the information about the skull housing the brain and facial structures.
Step-by-step explanation:
Finish the sentence: 1) the head, together with all its parts contains the brain and sensory organs. This is because the skull provides a bony framework for the head and consists of 22 different bones, including 8 in the cranium, which encloses the brain and 14 in the face. The cranial cavity is the specific space within the skull where the brain is located. The brain, a large organ composed of white and gray matter, is contained within the cranium and is continuous with the spinal cord. As the control center of the nervous system, the brain is responsible for processing sensory information, regulating bodily functions, and allowing us to think, learn, and remember.
