Early Development of Pig Embryo

This set of flashcards covers key concepts related to the early development of pig embryos, including embryonic structures, processes, and functions.

Mesonephric kidneys

Embryonic kidneys that function early to remove nitrogenous wastes.

Blastocyst

Early stage of embryonic development that forms after the morula, containing a cavity (blastocoel) and two cell groups: trophoblast and inner cell mass.

Gastrulation

Process in which the inner cell mass of the blastocyst forms the primary germ layers: ectoderm, mesoderm, and endoderm.

Neurulation

Developmental process where the neural tube forms from the ectoderm during early embryogenesis.

Septum Transversum

Transverse partition in embryos that separates the thoracic and abdominal cavities, eventually contributing to the diaphragm.

Somites

Segments of mesoderm that give rise to the vertebrae, ribs, and associated muscles of the body.

Trophoblast

Outer layer of cells in the blastocyst that implants into the uterine wall and contributes to the placenta.

Cranial flexures

Major curvature in the embryo, including mesencephalic, cervical, and tail flexures.

Placenta

Organ that provides nutrients and oxygen to the developing embryo and removes wastes, functioning as the interface between maternal and fetal blood.

Amnion

Thin membrane surrounding the embryo filled with amniotic fluid, providing protection and a moist environment.
