Vertebrate anatomy

The pharyngeal arches are structures seen in the development of vertebrates, are recognisable precursors for numerous structures.

The premaxilla (or praemaxilla) is one of a pair of small cranial bones at the very tip of the upper jaw of many animals, usually, but not always, bearing teeth.

In humans, the calcaneus (/kælˈkeɪniːəs/; from the Latin calcaneus or calcaneum, meaning heel) or heel bone is a bone of the tarsus of the foot which constitutes the heel.

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

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.

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.

The phalanges /fəˈlæŋdʒiːz/ (singular: phalanx /ˈfælæŋks/) are digital bones in the hands and feet of most vertebrates.

Temple indicates the side of the head behind the eyes.

The vomeronasal organ (VNO), or the Jacobson's organ, is an auxiliary olfactory sense organ that is found in many animals.

The mandible, lower jaw or jawbone (from Latin mandibula, "jawbone") is the largest, strongest and lowest bone in the face.

In human anatomy, the acromion (from Greek: akros, "highest", ōmos, "shoulder", plural: acromia) is a bony process on the scapula (shoulder blade).

The rib cage is an arrangement of bones in the thorax of all vertebrates except the lamprey and the frog.

The endocranium in comparative anatomy is a part of the skull base in vertebrates and it represents the basal, inner part of the cranium.

The squamosal is a bone of the head of higher vertebrates.

A rete mirabile (Latin for "wonderful net"; plural retia mirabilia) is a complex of arteries and veins lying very close to each other, found in some vertebrates, mainly warm-blooded ones.

A diastema (plural diastemata) is a space or gap between two teeth.

In biology, dactyly is the arrangement of digits (fingers and toes) on the hands, feet, or sometimes wings of a tetrapod animal.

In the embryonic development of vertebrates, pharyngeal pouches form on the endodermal side between the pharyngeal arches.
