When comparing maxillary and mandibular lateral incisors the mandibular incisor crown is wider mesio-distally than the mandibula
Viefleur [7K]

Answer:

Mammalian dentition is characterized by heterodonty, in which both the upper and lower teeth are differentiated morphologically into four types: flat, chisel-shaped incisors, conical canines, bicuspid premolars and multicuspid molars in the mesiodistal direction.

Explanation:.

  • <u>The mesiodistal crown:</u>dimension is the smallest of any maxillary teeth.The mesiodistal measurement of the pulp chamber is wider compared to the labiopalatal one. The periphery of the socket often dips down palatally, labially, mesially and distally to accommodate the shape of the root.
  • <u>Maxillary central incisor:</u>The general shape is similar to maxillary central incisor except that they are shorter and narrower. It has the most cervically located contact area of any incisor. The mesioincisal and distoincisal angles are more rounded than the corresponding angles of maxillary central incisor.
  • <u>Permanent mandibular central incisor:</u>The crown dimensions are the smallest of any tooth, it has bilaterally symmetrical crown, and the line angles are the sharpest of any tooth.It shows the shallowest labial developmental grooves, smoothest lingual surface contour and the least developed cingulum.

Advances in technology have enabled scientists and researchers to better study the evolutionary relationships between species. M
padilas [110]

Answer:

Embryology: the study of similarities in embryos of organisms to find common connections

Developmental biology:  the study of life cycles of organisms to find common

Molecular biology: the analysis and comparison of DNA to better understand relationships between species

comparative anatomy: the study of the anatomy of an organism to explain evolutionary similarity

Explanation:

Embryology can be described as the branch of biology in  which studies about the sex cells, the process of fertilization and the development of the fetus or embryo are made. The similarities between the embryos show evolutionary history among different organisms.

Developmental biology can be described as the branch of biology in which studies are made about the processes of growth and developmental procedures about organisms. Organisms belonging to different groups can also show developmental similarities if they have a common ancestor.

Molecular biology is the branch of biology which is related to the study of life on molecular level. At this level, similarities between the genome of organisms can be checked for evolutionary histories.

Comparative anatomy: It is the branch of biology in which organisms are studies based on the similarities and differences in their structures.
