The oral cavity contains the teeth and tongue. It is the opening through which food enters the body and where the process of digestion begins.
The dorsal cavity contains the spinal cord, which is part of the central nervous system. Every body cavity contains some structures of the nervous system.
Everything in your mouth. Oral means from the mouth. Cavity means opening or hole.
The bone with a large opening for the spinal cord to enter the cranial cavity is the occipital bone. This opening is known as the foramen magnum. It serves as a passageway for the spinal cord to connect with the brain, allowing for the integration of the central nervous system.

Dorsal cavity: The smaller of the two main body cavities, the larger being the ventral cavity. It contains the central nervous system (the brain and spinal cord).
Central vacuole.
The body has four major cavities: cranial cavity (contains the brain), thoracic cavity (contains the heart and lungs), abdominal cavity (contains the stomach and intestines), and pelvic cavity (contains the reproductive organs and bladder).
The posterior cavity, also known as the dorsal cavity, primarily contains the brain and spinal cord. The brain is housed within the cranial cavity, while the spinal cord is located in the vertebral cavity. Together, these structures are crucial for the central nervous system's function.
