Introduction to Anatomy
In the exploration of the intricate tapestry that is the human body, our journey begins with an understanding of anatomy. Anatomy, derived from the Greek words 'tome' (meaning 'cut') and 'ana' (meaning 'up'), so literally to cut up! Anatomy is the science that unravels the structural framework of living organisms. It is not merely a study of bones and muscles but a profound exploration into the symphony of life that orchestrates our existence. Anatomy is not only a way of studying a living organism, but also a language that allows us to better describe the complexities of the human form and pass the information on between generations.
In our introductory lesson, we will be acquainting ourselves with some directional terms that act as navigational guides of the human body. Terms like cranial and caudal delineate the orientation of structures, while external and internal speak to the relative positioning within the body's confines. All these terms will act as anchors when describing each intricate structure in the human body and will help us better locate and delineate each one from the other structures.
Delving deeper into the study of anatomy, we encounter the language of medicine, where every aspect has its own unique identifier in the form of Latin names. This linguistic precision is not a mere formality; as English is now a universal language, and most of the publications and studies are written in this language, Latin was originally the key to a universal understanding that transcends geographical boundaries and unites medical professionals in a shared lexicon.
As we embark on this odyssey into the realm of anatomy, remember that every term, every structure, is a thread in the narrative of our life as human beings, and the study of anatomy will be a ground pillar into better understanding not only the functioning of the human body but will guide us through studying the physiological and pathological principles as well. In the chapters to come, we will unravel the intricacies of organs, systems, and the breathtaking harmony that sustains the miracle of the human body.

N.A. - Anatomical nomenclature (l. Nomina Anatomica) - meaning, from the international anatomical term list
Acetabulum - A concave, cup-shaped socket in the pelvis where the head of the femur fits.
Apophysis -
1. A natural bone process arising from a distinct ossification center during development, eventually merging with the bone in later stages.
2. a bony process exclusively allocated for the articular process of a vertebra.
Areola -
1. A small, open space or circular area (often inflamed)
2. A circular, pigmented area on the center of the breast.
Blastocyst - An early stage of embryonic development characterized by a hollow fluid-filled structure. It forms about 5 days after fertilization.
Blastomere - Any of the cells produced by cleavage of a fertilized ovum, especially each of the cells formed in the early stages of embryonic development.
brevis - short; brief
Bursa - A small, fluid-filled sac filled with synovial fluid and located between tissues such as muscles, tendons, and bones. The purpose of a bursa is to reduce friction and provide a cushioning effect during movement.
chondral - cartilaginous tissue
Condyle - A rounded prominence at the end of a bone that forms part of a joint
cuneiform - wedge-shaped
cupula - a dome-shaped structure
Dermatome - A specific area of the skin that is innervated by the sensory fibers of a single spinal nerve.
Diaphysis - The proximal part of long bone; It is the cylindrical, tubular portion that makes up the main axis of the bone.
ectopic - excentric; out of (its normal) place
Ectoblast - The outermost germ layer of an embryo, giving rise to the epidermis and nervous tissue.
Endoblast - The innermost germ layer of an embryo, giving rise to the lining of the digestive and respiratory tracts.
Epiphysis - The distal parts of long bone, consisting of cancellous bone tissue and usually covered by a layer of articular cartilage.
Foetus (Fetus) - A developing mammal in utero, in humans after 2 months of development.
Gastrulation - The process during embryonic development in which the blastula reorganizes into a multilayered structure known as the gastrula, establishing the three primary germ layers.
Hallux - The big toe in humans.
Kyphosis - Excessive outward curvature of the upper spine, leading to a rounded back.
Lordosis - The inward curvature of the spine, primarily in the cervical (neck) and lumbar (lower back) regions. This curvature is considered a normal, but can be excessive in hyperlordosis (swayback).
Mesenchyme - A type of embryonic connective tissue that serves as the precursor for various tissues in the body. It is derived from the mesoderm, one of the three primary germ layers formed during early embryonic development.
Mesentery - A fold of the peritoneum that provides support and attaches the intestines to the abdominal wall, helping to keep them in place.
Mesoblast - The middle germ layer of an embryo, developing into connective tissues, muscles, and some organs.
Morula - A solid ball of cells formed by the division of a fertilized egg, occurring before the blastocyst stage.
Neurulation - The process by which the neural plate becomes the neural tube, leading to the development of the nervous system.
Olecranon - The bony prominence (the epiphysis) at the proximal end of the ulna, forming the point of the elbow.
Ontogenesis - The development and growth of an individual organism from the earliest stage to maturity.
Peritoneum - A serous membrane that lines the abdominal cavity and covers the abdominal organs. It consists of two layers: the parietal peritoneum, which lines the abdominal wall, and the visceral peritoneum, which covers the abdominal organs. Between these two layers is a potential space called the peritoneal cavity, which contains a small amount of serous fluid.
Process - A projection or an outgrowth of tissue.
quadratus - square or rectangular
rostral - depending on the context, it may refer to a location or structure that is located toward the front or anterior part of an organism, or that is on the upper side (cranial) of the body.
Scoliosis - An abnormal lateral curvature of the spine that resembles an "S" or "C" shape.
Ulna - One of the two long bones in the forearm, located on medial (inner) side.
Zygote - The initial cell formed when two gamete cells (sperm and egg) fuse during fertilization. It marks the beginning of the development of a new organism. The zygote contains the full set of chromosomes, with half contributed by the sperm and half by the egg.
