What body cavities are located posterior to the diaphragm?
The abdominopelvic cavity is the inferior portion of the ventral cavity located below the diaphragm, as highlighted in red below. As the name suggests, the abdominopelvic cavity is in the abdomen and pelvis and consists of both the abdominal cavity and pelvic cavity.
Which body cavities are anterior or ventral?
The ventral body cavity is a human body cavity that is in the anterior (front) aspect of the human body. It is made up of the thoracic cavity, and the abdominopelvic cavity. The abdominopelvic cavity is further divided into the abdominal cavity and pelvic cavity, but there is no physical barrier between the two.
What divides the body into anterior and posterior?
The frontal plane is the plane that divides the body or an organ into an anterior (front) portion and a posterior (rear) portion. The frontal plane is often referred to as a coronal plane.
What is the difference between the posterior dorsal and the anterior ventral body cavities?
Anterior (or ventral) Describes the front or direction toward the front of the body. The toes are anterior to the foot. Posterior (or dorsal) Describes the back or direction toward the back of the body.
Where is the posterior located?
backPosterior or dorsal - back (example, the shoulder blades are located on the posterior side of the body). Medial - toward the midline of the body (example, the middle toe is located at the medial side of the foot).
What are the two body cavities within the posterior aspect and what does each cavity contain?
In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity (or vertebral cavity) encloses the spinal cord.

What is the body cavity?
A. body cavity. is a fluid-filled space inside the body that holds and protects internal organs. Human body cavities are separated by membranes and other structures. The two largest human body cavities are the ventral cavity and dorsal cavity. These two body cavities are subdivided into smaller body cavities.
What are the two largest cavities in the human body?
The two largest human body cavities are the ventral cavity and dorsal cavity. The ventral cavity is at the anterior (or front) of the trunk. It is subdivided into the thoracic cavity and abdominopelvic cavity. The dorsal cavity is at the posterior (or back) of the body, and includes the head and the back of the trunk.
What is the spinal cord?
is a very long, narrow cavity inside the vertebral column. It runs the length of the trunk and contains the spinal cord. The brain and spinal cord are protected by the bones of the skull and the vertebrae of the spine. They are further protected by the , a three-layer membrane that encloses the brain and spinal cord.
What is the brain in Figure 7.6.1?

The brain is arguably the most important organ in the human body. Fortunately for us, the brain has its own special “container,” called the cranial cavity. The cranial cavity enclosing the brain is just one ...
What is the brain's container?
Fortunately for us, the brain has its own special “container,” called the cranial cavity. The cranial cavity enclosing the brain is just one of several cavities in the human body that form “containers” for vital organs.
Which cavity holds the heart?
The pleural cavities hold the lungs, and the pericardial cavity holds the heart. fills the lower half of the trunk and is subdivided into the abdominal cavity and the pelvic cavity. The abdominal cavity holds digestive organs and the kidneys, and the pelvic cavity holds reproductive organs and organs of excretion.
What is the Dorsal Cavity?
In the human body, there are two major cavities- the ventral cavity and the dorsal, or posterior, cavity. Dorsal refers to the anatomical orientation towards the posterior or back portion of the body. In humans, for example, the scapula (shoulder blades) would be located on the dorsal side of the body. Therefore, the dorsal cavity is the region located on the posterior or back side of the human body. Of the two major body cavities, the dorsal cavity is smaller than the ventral cavity.
What are the bones of the cranial cavity?
This cavity is enclosed by the eight cranial bones: the frontal, occipital, sphenoid, ethmoid, parietal (x2), and temporal (x2) bones. Within the cranial cavity are the brain, the meninges, and the cerebrospinal fluid. The cranial cavity has four divisions corresponding to the gross anatomy of the human brain: the cerebrum, cerebellum, diencephalon, and brainstem. The cerebrum represents the largest portion of the brain and consists of the four major lobes of the brain- the frontal, parietal, temporal, and occipital lobes. The cerebellum lies below the cerebrum and aids in the coordination of movement and fine motor skills. Below the cerebellum, the diencephalon consists of two main parts- the thalamus and the hypothalamus. The brainstem represents the final division of the cranial cavity; the brainstem possesses three divisions: the midbrain, pons, and medulla oblongata.
What are the three layers of the dorsal cavity?
The dorsal cavity is lined by the meninges. The meninges consist of three layers: the pia mater, a delicate inner layer; the arachnoid mater, the middle web-like layer; and the dura mater, the tough outer layer. In addition to protecting the central nervous system (CNS), the meninges help to protect the organs of the CNS from mechanical trauma and provide the support structure for blood vessels in the dorsal cavity. The pia mater, the innermost layer, contains blood vessels which provide oxygen and nutrients to the brain and spinal cord. The arachnoid mater, the middle layer, contains cerebrospinal fluid to cushion the brain and spinal cord. The dura mater, or outer layer, supports the vascular supply feeding the brain and helps to prevent the entry of external pathogens which could lead to infection of the central nervous system.
What are the two cavities that surround the dorsal cavity?
In humans, the dorsal cavity is comprised of two distinct yet interconnected cavities: the cranial cavity and the vertebral, or spinal, cavity . The dorsal cavity is lined by the meninges, a specialized membrane consisting of three layers which protect the brain and the spinal cord. The meninges will be further discussed below in this lesson.
Where is the ventral cavity located?
The human body consists of two major body cavities: the ventral and the dorsal cavities. The ventral cavity is located at the anterior or front of the body, while the dorsal cavity is located at the posterior or back of the body.
What is the most narrow cavity in the human body?
The vertebral cavity is located along the posterior or back of the human body. It represents the most narrow cavity within the human body. Also known as the spinal cavity, the vertebral cavity is enclosed within the 33 bones of the vertebral column. These vertebrae are divided into five sections: the cervical, thoracic, and lumbar regions, and the sacrum and coccyx bones. The cervical region consists of 7 vertebrae in the neck. The thoracic region, located mid-back, contains 12 vertebrae and represents the longest division of the vertebral cavity . The lumbar region, or lower back, consists of 5 vertebrae, while the sacrum and coccyx, both consisting of fused bones, form the pelvic girdle and the pelvic floor. The vertebral cavity contains the spinal cord, the meninges, and the cerebrospinal fluid.
Retroperitoneal Organs
The abdominal cavity is the large space that is vertically enclosed by the vertebral column and abdominal muscles, and horizontally by the diaphragm and pelvis. The peritoneum is a serous membrane that lines the abdominal cavity and supports the abdominal organs.
Where is the Retroperitoneal Cavity?
The intraperitoneal space is the part of the abdominal cavity that is surrounded by the peritoneum, and houses organs such as the stomach and the intestines. The retroperitoneal cavity is the space located behind the intraperitoneal space where the kidneys are located.
A Mnemonic for Retroperitoneal Organs
The retroperitoneal organs mnemonic SAD PUCKER can be used to summarize retroperitoneal organs.
The Structure of Retroperitoneal Organs
The retroperitoneum is divided into three main spaces anatomically, which house different retroperitoneal structures:
