what are the two main divisions of the ventral body cavity?

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.

Why are invertebrates usually dissected from the dorsal side while vertebrates are dissected from the ventral side? ... A protostomes have two major nerve chords on the ventral side of their body. Deuterostomes have one major nerve chord on the dorsal side of their body. So you cut a deuterostome on the ventral side.

Tutorial 16: Major Divisions of the Vertebrate Brain. The vertebrate brain is divided into three major divisions, the hindbrain, midbrain, and forebrain. The structure and function of the hindbrain and midbrain in humans is very similar to those in lower animals.

The serous membranes are: Peritoneum — the peritoneal cavity is found within the abdominal & pelvic body cavities. Connecting peritoneum forms: — mesentery — ligament. Pleura — two pleural cavities (separated by mediastinum) are found within the thoracic cavity.

In most bilateral animals the eyes and other sense organs are located up front, on the head. Flatworms are the simplest animals to have three tissue layers: the ectoderm, mesoderm, and endoderm (Figure 23-9). ... Planarians have three tissue layers (shown above) and are bilaterally symmetrical.

The thoracic cavity is the anterior ventral body cavity found within the rib cage in the torso. It houses the primary organs of the cardiovascular and respiratory systems, such as the heart and lungs, but also includes organs from other systems, such as the esophagus and the thymus gland.

['Primarily retroperitoneal organs developed and remain outside of the parietal peritoneum. The oesophagus, rectum and kidneys are all primarily retroperitoneal.', 'Secondarily retroperitoneal organs were initially intraperitoneal, suspended by mesentery.']

The coronal or frontal planes divide the body into front and back (also called dorsal and ventral or posterior and anterior) sections and are x-y planes. The transvers planes, also known as the axial or horizontal planes, are parallel to the ground and divide the body into top and bottom parts.

The body cavities house and protect the internal organs. There are two main body cavities: the dorsal cavity and the ventral cavity.

The possession of a body cavity has two major advantages. Whereas organs that lie in solid tissue are squeezed or compressed every time the animal moves, a body cavity permits them freedom of movement, for example providing for more efficient transport of gut contents.

The skeleton is traditionally divided into two major parts: the axial skeleton, which includes the skull, spine, and rib cage; and the appendicular skeleton, which includes the appendages and the girdles that attach them to the axial skeleton.

Mollusk Body Plans. The mollusk body can generally be divided into three regions: the head, the foot, and a cluster of internal organs called the visceral mass. The visceral mass includes many of the organs mentioned in the previous concepts such as the stomach, the heart, the nephridia, and the gonads.

The thoracic cavity contains the heart, the lungs, and some abdominal organs. The thoracic cage provides attachments for muscles of the neck, thorax, upper limbs, abdomen, and back. The thorax moves up and down to allow breathing, so it is one of the most dynamic regions of the body.

Taxonomic level: phylum Nematoda; grade of construction: organs derived from three tissue layers; symmetry: bilateral; type of gut: complete; type of body cavity other than gut: pseudocoel; segmentation: absent; circulatory system: present; nervous system: small bundles of nerves (ganglia), two nerve cords; excretion: ...

Rat Diaphragm Tissue Sections The diaphragm divides the chest cavity from the abdominal cavity in mammals through a partition of skeletal muscle and connective tissue. The breastbone and backbone serve as sites of diaphragm attachment as does a centralized aponeurotic tendon.

Humans have four body cavities: (1) the dorsal body cavity that encloses the brain and spinal cord; (2) the thoracic cavity that encloses the heart and lungs; (3) the abdominal cavity that encloses most of the digestive organs and kidneys; and (4) the pelvic cavity that encloses the bladder and reproductive organs.
