Irregular bone

Index Irregular bone

The irregular bones are bones which, from their peculiar form, cannot be grouped as long, short, flat or sesamoid bones. [1]

24 relations: Bone, Coccyx, Ethmoid bone, Flat bone, Human skeleton, Hyoid bone, Inferior nasal concha, Long bone, Mandible, Maxilla, Palatine bone, Pharynx, Sacrum, Sesamoid bone, Short bone, Skeletal muscle, Skull, Sphenoid bone, Spinal cord, Temporal bone, Tongue, Trachea, Vertebra, Zygomatic bone.

Bone

A bone is a rigid organ that constitutes part of the vertebrate skeleton.

Coccyx

The coccyx, commonly referred to as the tailbone, is the final segment of the vertebral column in humans and apes, and certain other mammals such as horses.

Ethmoid bone

The ethmoid bone (from Greek ethmos, "sieve") is an unpaired bone in the skull that separates the nasal cavity from the brain.

Flat bone

Flat bones are bones whose principal function is either extensive protection or the provision of broad surfaces for muscular attachment.

Human skeleton

The human skeleton is the internal framework of the body.

Hyoid bone

The hyoid bone (lingual bone or tongue-bone) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage.

Inferior nasal concha

The inferior nasal concha (inferior turbinated bone or inferior turbinal/turbinate) is one of the turbinates in the nose.

Long bone

The long bones are those that are longer than they are wide.

Mandible

The mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human face.

New!!: Irregular bone and Mandible · See more »

Maxilla

The maxilla (plural: maxillae) in animals is the upper jawbone formed from the fusion of two maxillary bones.

Palatine bone

The palatine bones are two irregular bones of the facial skeleton in many animal species.

Pharynx

The pharynx (plural: pharynges) is the part of the throat that is behind the mouth and nasal cavity and above the esophagus and the larynx, or the tubes going down to the stomach and the lungs.

Sacrum

The sacrum (or; plural: sacra or sacrums) in human anatomy is a large, triangular bone at the base of the spine, that forms by the fusing of sacral vertebrae S1S5 between 18 and 30years of age.

Sesamoid bone

In anatomy, a sesamoid bone is a bone embedded within a tendon or a muscle.

New!!: Irregular bone and Sesamoid bone · See more »

Short bone

Short bones are designated as those bones that are as wide as they are long.

New!!: Irregular bone and Short bone · See more »

Skeletal muscle

Skeletal muscle is one of three major muscle types, the others being cardiac muscle and smooth muscle.

Skull

The skull is a bony structure that forms the head in vertebrates.

New!!: Irregular bone and Skull · See more »

Sphenoid bone

The sphenoid bone is an unpaired bone of the neurocranium. It is situated in the middle of the skull towards the front, in front of the temporal bone and the basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended.

Spinal cord

The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

New!!: Irregular bone and Spinal cord · See more »

Temporal bone

The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex.

New!!: Irregular bone and Temporal bone · See more »

Tongue

The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication, and is used in the act of swallowing.

New!!: Irregular bone and Tongue · See more »

Trachea

The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs.

New!!: Irregular bone and Trachea · See more »

Vertebra

In the vertebrate spinal column, each vertebra is an irregular bone with a complex structure composed of bone and some hyaline cartilage, the proportions of which vary according to the segment of the backbone and the species of vertebrate.

New!!: Irregular bone and Vertebra · See more »

Zygomatic bone

In the human skull, the zygomatic bone (cheekbone or malar bone) is a paired bone which articulates with the maxilla, the temporal bone, the sphenoid bone and the frontal bone.
