Muscle Tissue, Glands, and Anatomical Planes

A collection of vocabulary flashcards covering skeletal, cardiac, and smooth muscle tissues, exocrine and endocrine glands, and the primary anatomical planes of the human body.

Skeletal Muscle

Muscle attached to bones that allows the body to move; it is voluntary (consciously controlled) and striated.

Cardiac Muscle

Muscle found only in the heart that contracts to pump blood throughout the body; it is involuntary and striated.

Smooth Muscle

Muscle found in the walls of organs and tubes (such as the stomach, intestines, bladder, and blood vessels); it is involuntary and not striated.

Exocrine Gland

A gland that releases its products through ducts (tubes) to a specific location, such as sweat and salivary glands.

Endocrine Gland

A gland that releases hormones directly into the bloodstream without using ducts.

Anatomical Planes

Imaginary flat surfaces used to divide the body into sections and describe body structures.

Sagittal Plane

An anatomical plane that divides the body into left and right portions.

Midsagittal Plane

A sagittal plane that divides the body into equal left and right halves.

Parasagittal Plane

A sagittal plane that divides the body into unequal left and right portions.

Frontal (Coronal) Plane

An anatomical plane that divides the body into front (anterior) and back (posterior) portions.

Transverse Plane

An anatomical plane that divides the body into top (superior) and bottom (inferior) portions.
