Divisions of anatomy Gross anatomy Muscles that can be seen by the eye E.g., muscles, bones etc Microscopic anatomy Cannot be seen by the eye. Needs a microscope. Cytology= study of cells Histology= study of tissues. Ways to study anatomy. Regional anatomy- studying one region at a time and learning everything about it. Systemic anatomy- study one body system at a time. There are 11 systems in the human body. Anatomical position: standing, head facing forward and arms to the side. Palms facing forward with fingers extended and thumb pointing away from the body. Feet are slightly spaced apart with toes pointing forward. Anatomical Planes and sections- important when viewing scans. Planes are used in anatomy to describe the structure in 3D. Sagittal plane divides the body into right and left planes. Parasagittal is when it’s not directly through the middle. Midsagittal is when the plane is directly in the middle. Frontal plane divides the body into front and back sides. Transverse plane cut straight across the body and divides into upper and lower portions. Directional terms in anatomy Superior: towards the top of the head Inferior: towards the feet Distal: the furthest point from the origin of the body part such as fingers Proximal: closer to the point of the origin of the body part Anterior/ ventral: the front of the body Posterior/dorsal: the back of the body Medial: towards the median Lateral: away from median Cranial: towards the head Body cavities- 2 main cavities Dorsal cavity which subdivides into cranial and spinal cavity Ventral cavity is divides into thoracic and abdominal cavity.
