BIOL 143 Active Recall Vocabulary

Vocabulary flashcards covering epithelial, connective, muscle, and neural tissue concepts from the BIOL 143 study sheet.

APICAL

Top/free surface of epithelial tissue.

STRATIFIED

Epithelium arranged in multiple layers.

BASEMENT MEMBRANE

Bottom side of epithelial tissue.

MACROPHAGE

Immune cell associated with getting rid of unwanted material, debris, or cells.

GROUND SUBSTANCE

Material that fills the spaces between connective-tissue cells and fibers.

INTERCALATED DISCS

Structures that connect cardiac muscle cells.

FIBROBLAST

Connective-tissue cell that makes/secretes fibers.

FIBERS

Protein components of connective tissue.

LOOSE CONNECTIVE TISSUE

Connective tissue with loosely arranged cells and fibers.

DENSE CONNECTIVE TISSUE

Connective tissue with densely packed fibers.

ADIPOSE TISSUE

Tissue dominated by fat-storing adipocytes.

ADIPOCYTE

Fat-storing cell.

TRIGLYCERIDE

Stored fat/energy molecule from your guide.

LACUNA

Small cavity where an osteocyte sits.

CANALICULI

Tiny channels in compact bone.

Simple squamous

Thin, one layer structure that allows rapid exchange.

Simple cuboidal / columnar

Tissue with more cytoplasm that functions in absorption and secretion.

Stratified squamous

Tissue with many layers providing protection against abrasion.

Connective tissue

Extracellular matrix and fibers that support, bind, cushion, and resist force.

Adipose

Large lipid-filled adipocytes functioning in energy storage and cushioning.

Blood

Fluid plasma matrix for transport of cells and dissolved substances.

Cartilage

Firm, flexible matrix providing support while tolerating compression.

Bone

Mineralized matrix arranged in osteons providing strong support and protection.

Skeletal muscle

Long, striated contractile fibers that allow forceful voluntary movement.

Smooth muscle

Tapered, unstriated cells providing involuntary contraction in internal structures.

Cardiac muscle

Branched, striated cells with intercalated discs for coordinated heart contraction.

Neuron

Cell where dendrites receive signals and the axon carries signals away for directional communication.
