Embryology (from Greek ἔμβρυον, embryon, 'the unborn, embryo'; and -λογία, -logia) is the branch of zoology that studies the prenatal development of gametes (sex cells), fertilization and development of embryos and fetuses. It is a subset of, and predecessor to, developmental biology. Embryology includes teratology, the study of congenital disorders that occur before birth.
Early embryology, put forward by Marcello Malpighi, was preformationist in concept: based on the idea that organisms develop from pre-existing miniature versions of themselves. The theory now accepted, epigenesis, is the idea that organisms develop from seed or egg in a sequence of steps. This concept was proposed in antiquity by Aristotle. Modern embryology developed from the work of Karl Ernst von Baer, though accurate observations had been made in Italy by anatomists such as Ulisse Aldrovandi and Leonardo da Vinci in the Renaissance.
How this connects to Human Anatomy
To study this topic responsibly, identify its normal structure or function, distinguish the main mechanism from its observable consequences, and ask which data can test a competing explanation. The subject foundations below outline these connections without pretending to be a specialist textbook chapter.

What the underlying subject studies
Anatomy describes the three-dimensional organization of the human body. Start by placing the structure in a region, identifying boundaries and neighboring organs, and tracing its vascular supply and innervation. A drawing viewed from the front does not necessarily show the patient’s left and right in the same places as an axial scan.
How mechanisms and evidence connect
Link gross anatomy to histology and embryological origin when they help explain function. A nerve, muscle, vessel or organ cannot be understood from its name alone: its course, attachments and relationships provide the practical meaning. Anatomic variation and imaging orientation must always be considered.
How to develop a sound explanation
For revision, sketch a region from memory, label its principal structures, and compare your drawing with an approved anatomical atlas. A conceptual diagram is useful for relationships but cannot represent precise surgical anatomy or all anatomical variants.
