  2. Pterygomandibular space - Wikipedia

    en.wikipedia.org/wiki/Pterygomandibular_space

    The pterygomandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the head and is paired on each side. It is located between the lateral pterygoid muscle and the medial surface of the ramus of the mandible. The pterygomandibular space is one of the four ...

  3. Facet joint - Wikipedia

    en.wikipedia.org/wiki/Facet_joint

    The facet joint is the joint between the inferior articular process (labeled at bottom) and the superior articular process (labeled at top) of the subsequent vertebra. The facet joints (also zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae.

    en.wikipedia.org/wiki/Body_cavity

    FMA. 85006. Anatomical terminology. [ edit on Wikidata] A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity.

  5. Fascial spaces of the head and neck - Wikipedia

    Fascial spaces (also termed fascial tissue spaces [1] or tissue spaces [2]) are potential spaces that exist between the fasciae and underlying organs and other tissues. [3] In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection. The fascial spaces can also be opened during ...

    A ring torus with aspect ratio 3, the ratio between the diameters of the larger (magenta) circle and the smaller (red) circle. In geometry, a torus ( pl.: tori or toruses) is a surface of revolution generated by revolving a circle in three-dimensional space one full revolution about an axis that is coplanar with the circle.

  7. Z series space suits - Wikipedia

    en.wikipedia.org/wiki/Z_series_space_suits

    Z series space suits. The Z-1 is the first Z prototype suit constructed. The Z series [1] is a series of prototype extra-vehicular activity (EVA) space suits being developed in the Advanced Extravehicular Mobility Unit (AEMU) project under NASA's Advanced Exploration Systems (AES) program. The suits are being designed to be used for both micro ...

  8. Anatomical plane - Wikipedia

    en.wikipedia.org/wiki/Anatomical_plane

    t. e. An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human and non-human anatomy, three principal planes are used: The sagittal plane or lateral plane ( longitudinal, anteroposterior) is a plane parallel to the sagittal suture.

  9. Zygomatic arch - Wikipedia

    en.wikipedia.org/wiki/Zygomatic_arch

    In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); the tendon of the temporal muscle ...
