vertebrae    音標拼音: [v'ɚtəbr,e]
vertebra的復數形

vertebra的復數形

Vertebra \Ver"te*bra\ (v[~e]r"t[-e]*br[.a]), n.; pl.
{Vertebrae}. [L. vertebra, fr. vertere to turn, change. See
{Verse}.]
[1913 Webster]
1. (Anat.) One of the serial segments of the spinal column.
[1913 Webster]

Note: In many fishes the vertebrae are simple cartilaginous
disks or short cylinders, but in the higher vertebrates
they are composed of many parts, and the vertebrae in
different portions of the same column vary very
greatly. A well-developed vertebra usually consists of
a more or less cylindrical and solid body, or centrum,
which is surmounted dorsally by an arch, leaving an
opening which forms a part of the canal containing the
spinal cord. From this dorsal, or neural, arch spring
various processes, or apophyses, which have received
special names: a dorsal, or neural, spine, spinous
process, or neurapophysis, on the middle of the arch;
two anterior and two posterior articular processes, or
zygapophyses; and one or two transverse processes on
each side. In those vertebrae which bear well-developed
ribs, a tubercle near the end of the rib articulates at
a tubercular facet on the transverse process
(diapophysis), while the end, or head, of the rib
articulates at a more ventral capitular facet which is
sometimes developed into a second, or ventral,
transverse process (parapophysis). In vertebrates with
well-developed hind limbs, the spinal column is divided
into five regions in each of which the vertebrae are
specially designated: those vertebrae in front of, or
anterior to, the first vertebra which bears ribs
connected with the sternum are cervical; all those
which bear ribs and are back of the cervicals are
dorsal; the one or more directly supporting the pelvis
are sacral and form the sacrum; those between the
sacral and dorsal are lumbar; and all those back of the
sacral are caudal, or coccygeal. In man there are seven
cervical vertebrae, twelve dorsal, five lumbar, five
sacral, and usually four, but sometimes five and rarely
three, coccygeal.
[1913 Webster]

2. (Zool.) One of the central ossicles in each joint of the
arms of an ophiuran.
[1913 Webster]

  • Vertebra - Wikipedia
    Vertebrae take their names from the regions of the vertebral column that they occupy There are usually thirty-three vertebrae in the human vertebral column — seven cervical vertebrae, twelve thoracic vertebrae, five lumbar vertebrae, five fused sacral vertebrae forming the sacrum and four coccygeal vertebrae, forming the coccyx
  • Vertebrae: The Bones of the Spinal Column - Spine Info
    The vertebrae are stacked on top of each other and separated by intervertebral discs, which act as shock absorbers The vertebrae provide structural support for the body but also protects the spinal cord, which runs through an opening in each vertebra called the vertebral foramen
  • The Vertebral Column - Joints - Vertebrae - Vertebral Structure
    The vertebral column (also known as the backbone or the spine), is a column of approximately 33 small bones, called vertebrae The column runs from the cranium to the apex of the coccyx, on the posterior aspect of the body
  • Vertebrae - Definition, Parts, Types and Function - Biology Dictionary
    Vertebrae are important structurally in vertebrates They support the head and neck, allowing movements such as turning the neck The vertebrae also provide attachment points for muscles and ligaments, allowing many of the motions that the body is able to go through, such as bending and twisting
  • Spine (Vertebral Column) – Bones, Anatomy, Labeled Diagram
    The vertebral column, commonly known as the spine, spinal column, or backbone, is a flexible hollow structure through which the spinal cord runs It comprises 33 small bones called vertebrae, which remain separated by cartilaginous intervertebral discs The vertebral column forms the axial skeleton, skull bones, ribs, and sternum
  • What Are The Different Types Of Vertebrae? - Science ABC
    The vertebral column is formed of four different types of vertebrae: the cervical vertebrae, the thoracic vertebrae, the lumbar vertebrae, and the sacrococcygeal vertebrae, in order from head to hip The skeleton is what supports and anchors the soft tissue of our body, such as muscles and skin
  • Anatomy of Vertebrae: Exploring Types and Their Functions
    Thoracic Vertebrae The thoracic vertebrae form the central segment of the vertebral column and are characterized by their articulation with the ribs This segment consists of twelve vertebrae, each serving as a point of attachment for a pair of ribs, which contribute to the protective framework of the thoracic cavity
