Unit 1 chapter 3 anatomy exam

cell membrane

Two major parts of a cell are the nucleus and

channels

The selective movement of ions through a membrane occurs through areas called

gap junctions

The cells in heart muscle are often held together by areas called

tight junctions

The inside lining of the digestive tract is lined with cells that are held together by

ribosome

What organelle contains enzymes that are associated with protein synthesis?

Golgi apparatus

functions to package molecules into vesicles that can be transported out of a cell.

endoplasmic reticulum

functions as a sac-like or tubular network of structures that provide transport.

mitochondrion

The organelle that is the source of most of the cellular energy is the

lysosomes

contain enzymes that are used to degrade foreign particles as well as cell structures

cilia

The structures that cause fluids and mucus to move across their surface are the

sperm

Which human cell is the only cell to possess a flagellum?

microfilaments

The protein actin is found in __ which results in some type of movement or contraction.

Inclusion

What is the term for chemical particles in a cell which appear lifeless and have no obvious function?

facilitated diffusion

Insulin usually increases the movement of glucose through a cell membrane by a process called

shrink

Hypertonic solutions tend to cause cells to

0.9%

Normal isotonic sodium chloride solution is

Filtration

The movement of a salt through a membrane, such as in a kidney, because of pressure differences is

active transport

Movement of molecules from low to high concentrations is

phagocytosis

The ability of leucocytes to engulf bacteria is due to the process of

Cytokinesis

The process , which divides the cytoplasmin half , is specifically termed

mitosis

The process that results in daughter cells with half of the original chromosome number is

interphase

At which stage does the chromosome number double?

metaphase stage

Chromosomes are aligned along the equatorial line during the

telophase

stage occurs when two daughter cells have completely formed

metastasis

Cancer cells can disseminate to other areas by a process called
