17
Q

The time between the embryonic period and parturition

A

Fetal period

18
Q

This is the born young or offspring of an animal that develops from the embryo

A

Fetus

19
Q

This is growth and development from birth to adult

A

Postnatal or postpartum development

20
Q

This is the formation of body structures and organs that requires cell division and cell differentiation

A

Embryogenesis or argonogenesis

21
Q

What are the two requirements in embryogenesis?

A

Cell division and cell differentiation

22
Q

The sheet of cells which give rise to all tissues and organs of the body

A

Germ layer

23
Q

What are the primary germ layers?

A
  1. ectoderm - outermost layer
  2. Mesoderm - middle layer
  3. Endoderm - innermost layer
24
Q

This type of tissue is composed of cells that dress on the basal lamina and closely together at the lateral surface

Also may differentiate into mesenchyme

A

Epithelium

25
Q

What are the two types of epithelium

A

Simple epithelium - single layer
Stratified epithelium - several layer

26
Q

This type of tissue which connects and support other tissues of the body

A

Connective tissue

27
Q

What are the two types of connective tissue?

A

Embryonic tissue - during the development of the embryo ex. Mesenchyme, mucoid

Adult connective tissue - areolar, dense, cartilage

28
Q

Type of tissue of loosely and irregularly embryonic cell separated by an extensive extra cellular matrix

Also, it present and differentiates into adult structures as the embryo gross

A

Mesenchyme

29
Q

Abnormalities that arise during prenatal development due to hereditary environment factors

A

Congenital malformations

30
Q

Position use in embryology

A
  • Dorsal
  • Ventral
  • cephalic - head of the embryo
  • Rostral
  • caudal
  • mesial - middle part of the embryo
  • Lateral - side of the embryo
31
Q

What do you call in the structures that have the same or similar function among species?

A

Homologous structures

32
Q

This study is all vertebrates share a basic pattern of organization also most noticeable during embryology

A

Comparative anatomy

33
Q

It is covered by the ectodermal epithelium

A

Body

34
Q

If is a long hollow structures that extend from the head to the tail, also along the body beneath the ectodermal epithelium

A

Neural tube

35
Q

Long hollow structures which runs the length near ventral midline of thebody

A

Gut tube or primitive gut

36
Q

It is the segmented portion of mass located lateral to the neural tube

A

Partial or dorsal mesoderm

37
Q

Narrow band of mesoderm lateral to paraxial mesoderm

A

Intermediate mesoderm

38
Q

Portion of mesoderm lateral to the intermediate mesoderm

A

Lateral mesoderm

39
Q

Long rod that extends from the head to the tail located at the middle line of the embryo

A

Notochord

40
Q

Slightly curved tube located in the ventral midline beneath the caudal part of the pharynx of the embryo

A

Head
