ossicle

Examples of ossicle in the following topics:

• Overview of the Axial Skeleton

  • It is composed of: the human skull, the ossicles of the middle ear, the hyoid bone of the throat, the rib cage (including the sternum), and the vertebral column.
  • The ossicles (also called auditory ossicles) are the three smallest bones in the human body.

• Reception of Sound

  • Interior to the tympanum is the middle ear, which holds three small bones called the ossicles ("little bones"), that transfer energy from the moving tympanum to the inner ear.
  • The three ossicles are the malleus (also known as the hammer), the incus (the anvil), and stapes (the stirrup).
  • The three ossicles are unique to mammals; each plays a role in hearing.
  • The ear ossicles are homologous to bones in a fish mouth; the bones that support gills in fish are thought to be adapted for use in the vertebrate ear over evolutionary time.
  • The middle ear contains three bones called ossicles that transfer the sound wave to the oval window, the exterior boundary of the inner ear.

• Human Axial Skeleton

  • The axial skeleton forms the central axis of the human body and includes the bones of the skull, the ossicles of the middle ear, the hyoid bone of the throat, the vertebral column, and the thoracic cage (ribcage) .
  • The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea.
  • The auditory ossicles consist of six bones: two malleus bones, two incus bones, and two stapes, one of each on each side.
  • The axial skeleton consists of the bones of the skull, ossicles of the middle ear, hyoid bone, vertebral column, and rib cage.

• The Axial Skeleton

  • Head, including the bones of the skull (cranium), face, auditory ossicles, and hyoid bone.
  • The ossicles (also called auditory ossicles) consist of three bones (malleus, incus, and stapes) that are the smallest in the body.

• Divisions of the Skeletal System: Axial and Appendicular

  • It is composed of the human skull, the ossicles of the middle ear, the hyoid bone of the throat, the rib cage, and the vertebral column .

• Phylum Echinodermata

  • Adult echinoderms exhibit pentaradial symmetry and have a calcareous endoskeleton made of ossicles, although the early larval stages of all echinoderms have bilateral symmetry .
  • As with all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles joined by connective tissue.

• Classes of Echinoderms

  • Like all echinoderms, sea cucumbers have an endoskeleton just below the skin: calcified structures that are usually reduced to isolated microscopic ossicles joined by connective tissue.

• Sensory Modalities

  • The ossicles (three tiny bones in the middle ear) pass the vibrations to the fluid-filled cochlea (a spiral, shell-shaped auditory organ of the inner ear).
