What does anterior and posterior mean in anatomy?
Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior 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 is the posterior view?
Posterior (or dorsal) Describes the back or direction toward the back of the body. Lateral describes the side or direction toward the side of the body. The thumb (pollex) is lateral to the digits. Medial describes the middle or direction toward the middle of the body. The hallux is the medial toe.
What bones are posterior?
Posterior View of the Skull Bones
- Parietal bone (os paritale)
- Occipital bone (os occipitale)
- Temporal bone (os temporale)
- Sphenoid (os sphenoidable)
What is the meaning of proximal and distal?
Proximal and distal: These two terms are almost always used in reference to relative locations of parts or places on the limbs. Proximal then refers to something closer to the torso while distal refers to parts and places away from the torso.
What is the anterior skeleton?
Most of the important bones and groups of bones in the human body are visible in the anterior view of the skeleton. The posterior view of the skeleton reveals bones that are obscured in the anterior view, most notably, the entire stack of individual vertebrae that span vertically from the sacrum to the skull.
What is the function of the anterior skeleton?
The bones of the skeleton provide support for the soft tissues. For example, the rib cage supports the thoracic wall. Most muscles of the body are attached to bones which act as levers to allow movement of body parts. The bones of the skeleton also serve as a reservoir for minerals, such as calcium and phosphate.
What is the anterior bone?
The major anterior skull bones include: Frontal bone, Mandible, Maxilla, Nasal bone, Parietal bone, Temporal bone, and Zygomatic bone. The foramen of the anterior skull include (top to bottom): Supraorbital foramen, Zygomatic foramen, Infraorbital foramen, and Mental foramen.
What are body positions?
The four main anatomical positions are: supine, prone, right lateral recumbent, and left lateral recumbent. Each position is used in different medical circumstances.
