The body cavities from superior to inferior starts with the cranial cavity. The vertebral cavity extends the entire length of the posterior axial skeleton. Inferior to the cranial cavity and anterior to the vertebral cavity is the thoracic cavity. All other cavities are anterior to the vertebral cavity as well. Inferior to the thoracic cavity is the abdominal cavity. The abdominal cavity is superior to the pelvic cavity. The pelvic cavity is the most inferior body cavity.
The nasal septum divides the medially into the right and left portion. The nasal septum separates the cranial cavity by the cribriform plate of the ethmoid bone and by the oral cavity by the hand palate. Passageways called the superior, middle and inferior meatuses are the nasal conchae or turbinate bone that curl out from the lateral walls of the nasal cavity on each side. Nasal conchae support the mucous membranes that line the nasal cavity that help increase the surface area. The upper posterior portion of the nasal cavity is slit like and lines and contains the factory receptors that give use the sense of smell. The rest of the cavity conducts air to and from the nasopharynx.

Some examples include the following: clavicle, coccyx, femur, fibula, foramen magnum, mandible, maxilla, metatarsals, ossify, phalanges, radius, scapula, sternum, suture, tibia, ulna, and vertebra. All of these terms are associated with the skeletal system. The mandible, maxilla, and foramen magnum are located in the cervical vertebrae. The clavicle, scapula, and sternum are located in the thoracic vertebrae. The lumbar vertebra contains the humerus, ulna, and radius. The coccyx is located in the sacral vertebrae. The femur, fibula, metatarsals, phalanges, and tibia are located in the appendicular skeleton. The sutures are located in the skull. The vertebrae is the backbone of the body. Ossification is the formation of bone. These terms are important in knowing and learning the skeletal system.
Remove the dorsal portion of the carapace to observe other organs in the head and thorax.
The name of the above diagram is called the Buccal Cavity. I am going to talk about each labelled structure in detail.
The endosteum is a connective tissue that protects cavities in long bones. The endosteum covers the surface of cancellous bone and the medullary cavity, unlike the periosteum the endosteum is not dense irregular connective tissue. (Clark, 2005)
1. Oral cavity, pharynx, (must also include accessory organs such as salivary glands, tongue, and teeth)
The axial skeleton is part of the skeleton that has bones from the head and the trunk which are found in the vertebrate, it forms the main axis or core of your skeletal system. It has 80 bones and is split into eight parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column. Ity kepps the heart and the lungs safe from any damge that the body might experience. It is also the portion of
Nasal Cavity- its a space within the nose and the skull with the mucus membrane which warms and moisturizes the air you breathe In that’s going in the body by passing through the nostrils before it passes into the nasopharynx, The human nose is divided into two parts the external nose and the internal nasal cavity. There are hair with the cavity that filters out dust, pollen and other foreign particles. Before the air passes into the two passages the nasal cavity.
Basic anatomical comparisons show that people have much more in common with herbivores than carnivores – or even omnivores! Just a look at an adult's mouth – let alone a child's – shows that the opening is too small for anything but relatively small pieces of food. We can't even swallow those whole, but must chew them finely and mix them with saliva before the ball of food will slide down the oesophagus. In contrast, carnivorous animals such as cats tear off chunks and swallow them almost immediately.
Dorsal cavity is located toward the backside of the body and it made of the cranial portion of the skull and vertebral column. The cranial cavity contains the brain where the vertebral column contains the spinal cord, which is an extension of the brain. The ventral cavity is located toward the front of the body and it is divided to two sections by the diaphragm muscle into upper (thoracic cavity) and lower (abdominopelvic cavity). The thoracic cavity has a two cavity inside it the pleural cavity that hold the lungs and the pericardial cavity that contains the heart. The thoracic cavity also contains the trachea, bronchi, and esophagus. The abdominopelvic cavity contains the stomach, liver, gallbladder, pancreas, the spleen, kidneys, and the
2. Thoracic cavity: thoracic means chest, this cavity is located in the anterior portion of the body and the mediastinum. It contains the cavity that surrounds the breast bone and ribs. Containing the lungs, heart, trachea, larynx and bronchial tubes.

The core is at the center of our bodies and is the link between the upper and lower
The core has been explained by few researchers as a cylinder with double walls, front being the abdominals, roof formed by the diaphragm, bottom being formed by the hip and pelvic floor muscles and back being the gluteals and the paraspinals. (2)
