Study Notes

Cells and Tissues

Cells are the smallest units of living matter
Cells form tissues
Tissues join together to form organs
Organs work together to form systems

Organs

Organs can be hollow (cavities) or solid
Hollow organs have a lumen (cavity)
Walls of hollow organs have multiple layers (tunics)
Innermost layer called the mucosa (viscera) or intima (blood vessels)
Middle layer is the muscularis
Outer layer is the adventitia
Solid organs have a capsule, stroma, and parenchyma
Capsule is a layer of connective tissue
Stroma is the supporting tissue
Parenchyma is the functional tissue

Body Planes

Body position uses three main planes (sagittal, transverse, frontal) used in anatomical studies
Sagittal plane divides the body into left and right halves
Midsagittal plane divides the body into equal halves
Frontal/coronal plane divides the body into front and back sections
Transverse plane divides the body into upper and lower sections
