The bones of the axial skeleton. Synapomorphy of the Vertebrata.
Repeated and interconnected bones that formed the main axial elements in the dorsal part of a skeleton. Can be classified as cervical, dorsal, sacral, and caudal, in order from cranially to caudally, and with each composed of a centrum, neural arch, and nerve canal.
The segments of the spinal column; separated by disks made of connective tissue (sing.: vertebra).
Spinal column; the backbone.
The spinal column consists of twenty-four small bones called vertebrae. Seven are located in the neck, twelve in the mid-back, and five in the lower back. The vertebrae stack one on top of the other and form a straight line when viewed from the front or back. It is rare to find someone with a perfectly aligned spine.
fairly ridged bone segments of the spine.
the cylindrical bones that comprise the spinal column
more than one bone of the spinal column.
the individual bones of the spinal column
the bones (there are 33 of them) which make up the spine. Each vertebra has a hole in its centre, so that when stacked on top of one another they form a long channel called the vertebral canal, through which the spinal cord runs.
The bones of the vertebral column, consisting of 5 sections (cervical, thoracic, lumbar, sacral and caudal). Some marine mammals do not have true sacral vertebrae.
bony structures that surround the spinal cord.
Bones that make up the spinal column.
any one of the thirty-three bony segments that make up the spinal column.
the bones of the spine and tail that protect the spinal cord.
bones that form the backbone vertebrate; an animal with a backbone
The 33 individual bones composing the backbone or spine.
The bony segments of the spinal column which contain and protect the spinal cord .
The 24 block-shaped bones that make up the vertebral column.
Twenty six separate bones which make up the spine. Creating strong but flexible support for the neck and trunk
Bones forming the spinal column.
the bones of the spinal column (backbone)
Form the backbone (aka spine or spinal column) and are ring-shaped and stack on top of one another. Each one is hard a hollow and is cushioned by disks. Weight bearing as tolerated
The 33 bones of the spine, 24 of which are single and jointed, the others being fused.
The individual bones of the spine, the sizes and shapes of which correspond to functional needs and location. In all, there are seven cervical, twelve thoracic, and five lumbar vertebrae. The sacrum consists of five vertebrae which are fused into one bone and the number of coccygeal bones is variable.
The 33 bones that form the spinal column and protect the spinal cord. There are 7 cervical, 12 thoracic, 5 lumbar and 5 sacral and the 4 coccyx.
one or twenty-four moveable segments of the human spinal column. Two vertebrae adjacent to each other form a motor unit.
one of the 31 bone segments of the spinal column.
The single bones or segments of the spinal column
Vertebrae are the bones of the spinal column.
The bones that make up the spine.
