Cellular Anatomy
This term describes the gelatinous, fluid material that fills the interior of a cell.
What is cytoplasm?
This specific cellular process is demonstrated when a white blood cell engulfs and destroys invading bacteria.
What is phagocytosis?
A cell spends the vast majority of its lifespan in this metabolic phase between active divisions.
What is interphase?
This type of tissue acts as the body's primary energy reservoir by storing and releasing fat molecules.
What is adipose tissue?
This specific category of double-layered membrane seals off internal body cavities that have no exposure to the outside world.
What is a serous membrane?
These specialized cellular sub-structures are distributed throughout the cell to perform specific tasks.
What are organelles?
When red blood cells are dropped into this type of highly concentrated solution, water rushes out, causing them to shrink.
What is a hypertonic solution?
During this initial phase of mitosis, the protective nuclear envelope completely dissolves.
: What is prophase?
These thin, flattened epithelial cells resemble flagstones or flat pancakes under a microscope.
What are squamous cells?
Lacking the striated patterns found in skeletal muscle, this involuntary contractile tissue lines the walls of your intestines.
What is smooth muscle?
These tiny, membrane-bound sacs function as the cellular shipping department, storing and moving cargo.
What are vesicles?
To receive chemical messages, target cells express these specialized binding structures on their outer surfaces.
What are receptors?
This mitotic stage is easily recognized because the duplicated sister chromatids align perfectly along the cell's equator.
What is metaphase?
These highly delicate, branching fibers weave together to build a supportive mesh network within organs and tissues.
What are reticular fibers?
These specialized, branching extensions of a neuron are custom-built to pick up incoming electrical signals.
What are dendrites?
Foreign invaders and waste are broken down inside the cell by digestive enzymes housed in these tiny sacs.
What are lysosomes?
This process forces materials across a biological membrane using mechanical or fluid pressure.
What is filtration?
This term describes the final separation of the cytoplasm, which occurs right after mitosis finishes to create two distinct cells.
What is cytokinesis?
Unlike epithelial sheets, the cells within connective tissues are distinctively separated by this abundant non-living material.
What is intercellular substance (or extracellular matrix)?
This specific serous membrane forms the protective outer lining of the abdominal cavity.
What is the parietal peritoneum?
Carrying hundreds or thousands of hereditary instructions, this specific unit dictates a cell's structure and operations.
What is a gene?
Epithelial tissue located along the lining of the digestive tract is specifically optimized to perform this action on digested nutrients.
What is absorption?
f a cell detects unrepairable genetic damage during its cycle, it can trigger this programmed, orderly process of self-destruction.
What is apoptosis?
Serving as the structural scaffolding of the human anatomy, almost every single organ relies on this broad tissue type for support.
What is connective tissue?
Mucous membranes, serous membranes, and the cutaneous membrane (skin) all belong to this major structural classification.
What are epithelial membranes?
