Lecture 3: Animal Architecture

Flashcards covering key vocabulary and concepts from Lecture 3 on Animal Architecture.

Protoplasmic Organization

Unicellular organisms that perform specific life functions.

Cellular Organization

Aggregation of cells with functional differentiation and division of labor; cells not organized into tissues.

Cell-Tissue Organization

Aggregation of cells into tissues with defined patterns or layers, but not complex enough to be considered organs.

Tissue-Organ Organization

Aggregation of tissues into defined organs, containing more than one type of tissue.

Organ-System Organization

Organs working together as a physiological system to perform specific functions.

Epithelial Tissue

Sheets of cells that cover external or internal surfaces.

Connective Tissue

Specialized tissues binding and supporting other tissues.

Muscular Tissue

Tissue specialized for movement, both voluntary and involuntary.

Nervous Tissue

Tissue specialized for reception and conduction of stimuli and impulses.

Simple Squamous Epithelium

Flattened cells facilitating short diffusion distance, found in capillaries and lung alveoli.

Transitional Epithelium

Stratified epithelium that accommodates stretching, found in the urinary tract and bladder.

Acoelomate

Organisms with no true coelom; space filled with parenchyma.

Pseudocoelomate

Organisms with a pseudocoelom; lack mesodermal lining.

Coelomate

Organisms with a true coelom lined with peritoneum derived from mesoderm.

Allometry

The study of biological scaling and how various biological aspects vary with body size.

Metabolic Rate (MR)

The amount of energy used by an organism per unit time.

Resting Metabolic Rate

The amount of energy expended by an animal at rest, influenced by body mass.
