Choice A rationale:

The spinal cord is not contained in the cranial cavity. The spinal cord is located within the spinal canal, which runs through the vertebral column, providing protection to the spinal cord.

Choice B rationale:

The heart is not contained in the cranial cavity. The heart is situated in the thoracic cavity, between the lungs, and is protected by the ribcage.

Choice C rationale:

The brain is contained in the cranial cavity. The cranial cavity, also known as the intracranial space, houses the brain and provides protection to this vital organ. The brain is the control center of the body, regulating various functions and processing sensory information.

Choice D rationale:

The stomach is not contained in the cranial cavity. The stomach is located in the abdominal cavity, which is situated below the diaphragm and above the pelvis. It is involved in the digestion of food and is not found in the cranial cavity.

Choice A rationale:

A suffix is a word part that is added to the end of a root word to modify its meaning. For example, in the medical term "cardiologist," the suffix '-ologist' means a specialist or expert. A suffix is placed at the end of a root word or a combining form to create a specific medical term.

Choice B rationale:

A word root is the foundational part of a medical term. It contains the core meaning of the term and is not usually modified by prefixes or suffixes. For instance, in the term "cardiology," 'cardi-' is the word root, representing the heart. Word roots provide the essential meaning of the medical term.

Choice C rationale:

A prefix is a word part that is added to the beginning of a root word or a combining form to modify its meaning. Prefixes are important in medical terminology as they indicate locations, numbers, or time. For example, in the term "prehypertension," the prefix 'pre-' means before. Prefixes are added at the beginning of a word.

Choice D rationale:

A combining form is a word root combined with a vowel (usually 'o') that can be joined with other word parts to create a medical term. Combining forms are used as a connector to join a root word and a suffix or another root word. For example, in the term "gastritis," 'gastr-' is the combining form, representing the stomach. Combining forms facilitate the construction of complex medical terms.
