This is the standard body orientation with the body upright, arms at the side, and palms facing forward.
Anatomical Position
These are the four primary tissue classes of the body.
Epithelial, Connective, Muscular, Nervous
These are the two main layers of the skin.
Epidermis and Dermis
These are the functions of the skeletal system (name at least 3).
Support, protection, movement, mineral storage, blood formation, fat storage
This type of joint classification includes fibrous, cartilaginous, and synovial joints.
Structural Classifications
This body plane divides the body into left and right sections.
Sagittal
This tissue type is avascular, tightly packed, and has a high rate of mitosis.
Epithelial
This layer of the epidermis is present only in thick skin like the palms and soles.
Stratum Lucidum
These are the shaft and ends of a long bone.
Diaphysis and Epiphysis
This type of synovial joint allows multiaxial movement (such as the shoulder).
Ball-and-Socket
These two directional terms mean “toward the midline” and “away from the midline.”
medial is toward the midline and lateral is away from the midline
This component of connective tissue consists of protein fibers and ground substance.
Extracellular Matrix
This pigment, along with hemoglobin and carotene, contributes to normal skin color.
Melanin
These are the four bone cell types found in osseous tissue.
Osteoclasts, Osteocytes, Osteoblasts, Osteogenic cells
This term means returning the thumb to its anatomical position after opposition.
Reposition
These two regions divide the body into the head/neck/trunk and the limbs.
These tissue cells include fibroblasts, leukocytes, adipocytes, chondrocytes, and osteocytes.
Connective Tissue Cells
This layer of the dermis is made of dense irregular connective tissue and provides strength and elasticity.
Reticular Layer
This type of bone is found in epiphyses and contains trabeculae filled with marrow.
Spongy Bone
This trunk movement bends the spine sideways.
Lateral Flexion
These four quadrants are used to describe abdominal organ locations.
Right Upper Quadrant
Left Upper Quadrant
Right Lower Quadrant
Left Lower Quadrant
These junctions act as tunnels between cells, allowing ions and small molecules to pass directly between them.
Gap Junctions
This abnormal skin color results from bilirubin buildup.
Jaundice
These two cells mediate bone mineralization and bone resorption.
Osteoblasts (mineralization) and Osteoclasts (resorption)
This is the standard starting position where all joint angles are considered to be at 0°
