What are the 2 major cavities of the body and their structure?

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.

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 are the main cavities of the body?

The Human Body Cavities

• Dorsal body cavity–the cranial cavity and the spinal cavity in combination.
• Cranial cavity–the space occupied by the brain, enclosed by the skull bones.
• Spinal cavity–the space occupied by the spinal cord enclosed by the vertebrae column making up the backbone.

Which body cavities are anterior or posterior?

The dorsal (posterior) cavity and the ventral (anterior) cavity are the largest body compartments (Figure 4). These cavities contain and protect delicate internal organs, and the ventral cavity allows for significant changes in the size and shape of the organs as they perform their functions.

What is the anterior part of the body?

front
Anterior refers to the front of the human body when used to describe anatomy. The opposite of anterior is posterior, meaning the back of the human body. The term anterior is typically used in combination with other words that describe the location of a body part.

What does anterior mean in anatomy?

the front
Listen to pronunciation. (an-TEER-ee-er) In human anatomy, has to do with the front of a structure, or a structure found toward the front of the body.

What divides the ventral cavity in 2?

the diaphragm
The ventral cavity, in humans, is actually made up of two separate cavities, separated by the diaphragm, a thin muscle which helps control the expansion and contraction of the lungs.

What comprises ventral cavity?

The ventral cavity is at the anterior, or front, of the trunk. Organs contained within this body cavity include the lungs, heart, stomach, intestines, and reproductive organs. You can see some of the organs in the ventral cavity in Figure 10.5.

What body cavities are located anterior to the diaphragm?

The ventral cavity, the interior space in the front of the body, contains many different organ systems. The organs within the ventral cavity are also called viscera. The ventral cavity has anterior and posterior portions divided by the diaphragm, a sheet of skeletal muscle found beneath the lungs.

Which body cavities are dorsal or posterior?

The dorsal cavity is at the posterior, or back, of the body, including both the head and the back of the trunk. The dorsal cavity is subdivided into the cranial and spinal cavities. The cranial cavity fills most of the upper part of the skull and contains the brain.

Which organs are located in the posterior body cavity quizlet?

Posterior Cavity (contains the brain and spinal cord).

What are the five major body cavities?

– cranial cavity. contains the brain. – vertebral cavity. contains the spinal cord. – diaphragm. muscle that separates the thoracic and abdominopelvic cavities. – thoracic cavity. enclosed by the ribs, sternum, and vertebral column. – pericardial cavity. – pleural cavity. – mediastinum. – abdominopelvic cavity.

What body cavities are located in abdominopelvic?

The abdominopelvic cavity is subdivided into the abdominal cavity and pelvic cavity. The abdominal cavity contains digestive organs, while the pelvic cavity contains the urinary bladder, internal reproductive organs and rectum Left Upper Quadrant (LUQ) One of the four quadrants into which the abdominopelvic area is divided.

What divides the body into anterior and posterior?

The median plane is a vertical plane that divides the body into equal right and left halves, and any vertical plane that is parallel to the median plane is known as the sagittal plane. The coronal plane is a plane that separates the body into anterior and posterior parts and is sometimes known as the ‘frontal plane.

What are the major body cavities and their subdivisions?

Fiber-rich fruits and vegetables. Foods with fiber help keep your teeth and gums clean,says the American Dental Association (ADA).
