Directional Terminology
This term describes a structure being closer to the head or upper part of the body.
What is superior (or cranial)?
This regional term refers to the anterior area of the elbow, commonly used for venipuncture.
What is the antecubital region?
This system is responsible for filtering blood, removing nitrogenous wastes, and regulating water and electrolyte balance.
What is the urinary system?
This type of chemical bond forms when valence electrons are shared completely equally between two atoms.
What is a nonpolar covalent bond?
This double-membrane organelle is the primary site of ATP generation via aerobic cellular respiration.
What is the mitochondrion?
In the anatomical position, the thumb is located in this directional relation to the pinky finger.
What is lateral?
If a patient injures their lower back, the medical chart will note it as an injury to this specific anatomical region.
What is the lumbar region?
Producing blood cells through hematopoiesis and storing essential minerals are key functions of this organ system.
What is the skeletal system?
This weak attraction forms between a partially positive hydrogen atom of one polar molecule and a partially negative atom of another polar molecule.
What is a hydrogen bond?
This network of flattened sacs is studded with ribosomes and is responsible for modifying and routing newly synthesized proteins.
What is the rough endoplasmic reticulum?
This directional term is used exclusively for limbs to describe a structure being farther from the point of attachment to the trunk.
What is distal?
This regional anatomical term refers specifically to the armpit.
What is the axillary region?
This system acts as the fast-acting control center of the body, utilizing electrical signals to respond to internal and external changes.
What is the nervous system?
This type of bond is created by the electrical attraction between oppositely charged atoms after an electron transfer.
What is an ionic bond?
This structure acts as the cell's gatekeeper, regulating traffic using a selectively permeable phospholipid bilayer.
What is the plasma membrane?
The skin is located in this relationship to the underlying skeletal muscles.
What is superficial?
The anatomical term "crural" refers to this specific part of the lower limb.
What is the leg (anterior leg/shin)?
Hair, skin, and nails belong to this system, which forms the body's protective external covering.
What is the integumentary system?
Water molecules exhibit this specific type of bond internally because oxygen is highly electronegative and shares electrons unequally with hydrogen.
What is a polar covalent bond?
These small, non-membranous structures are the actual sites of protein synthesis and can be found free in the cytosol or bound to membranes.
What is a ribosome?
This specific anatomical plane divides the body into unequal left and right portions.
What is a parasagittal plane?
This regional term refers to the area of the neck.
What is the cervical region?
This system transports oxygen, carbon dioxide, nutrients, and hormones throughout the body via a network of vessels.
What is the cardiovascular system?
An atom that has gained one or more electrons during ionic bonding and carries a net negative charge is known by this specific term.
What is an anion?
This spherical organelle contains acidic digestive enzymes to break down worn-out cellular parts, foreign pathogens, and debris.
What is a lysosome?
