Lab 1 - LOA and Histology Flashcards

Vocabulary flashcards focusing on anatomical position, regional and directional terminology, body planes, body cavities, tissue membranes, and histology based on Lab 1 materials.

Anatomical Position

Standardized reference position of the human body where palms face anteriorly (forward), feet are parallel, arms are at sides, and eyes are open.

Acromial

Regional term referring to the point of the shoulder.

Hallux

Regional term referring to the big toe, or great toe.

Mental

Regional term referring to the region of the chin.

Olecranal

Regional term referring to the posterior aspect of the elbow.

Otic

Regional term referring to the region of the ear.

Palmar

Regional term referring to the palm of the hand.

Pedal

Regional term referring to the foot.

Plantar

Regional term referring to the sole of the foot.

Pollex

Regional term referring to the thumb.

Superior vs Inferior

Directional terms applied exclusively to the head and trunk.

Proximal vs Distal

Directional terms applied exclusively to the limbs.

Midsagittal Plane

Anatomical plane located directly in the middle of the body, dividing it into equal left and right halves.

Parasagittal Plane

Anatomical plane located off-center, dividing the body into unequal left and right portions.

Cutaneous Membranes

Tissue membrane represented by the skin; the only external and dehydrated (dry) membrane.

Serous Membranes

Double-layered tissue membranes consisting of a visceral layer and a parietal layer, including the pericardium, pleural, and peritoneal membranes.

Mucous Membranes

Tissue membranes that line all bodily openings, including the GI, respiratory, and urinary tracts.

Synovial Membranes

Tissue membranes composed of connective tissue only that produce synovial fluid.

Epithelial Tissue

Tissue type that lines or covers internal or external spaces; characterized as avascular, highly cellular, and low acellular.

Connective Tissue

Tissue type characterized by low cell density (low cellular) and high extracellular matrix/fiber content (highly acellular).

Stratified Squamous Epithelium

Type of epithelium that functions to provide abrasion resistance and waterproofing.

Loose Areolar Connective Tissue

Fibrous loose connective tissue located in muscle fascia and surrounding epithelial tissue.

Cartilage

Connective tissue type distinguished by a clear ground substance and chondrocytes located inside lacunae.

Dorsal Body Cavity

Body cavity containing the cranial cavity (housing the brain) and the vertebral cavity (housing the spinal cord).

Ventral Body Cavity

Body cavity containing the thoracic cavity and the abdominopelvic cavity.
