Question 1

What is the largest organelle,responsible for cell reproduction and control of other organelles?

Accepted Answer

The nucleus is the largest organelle in most cells and is responsible for controlling the cell's activities and reproduction by housing the cell's DNA.

Question 2

The four phases of cell division all occur in:

Accepted Answer

The four phases of cell division (prophase, metaphase, anaphase, and telophase) all occur in mitosis, which is the process by which a cell divides its nucleus and contents to produce two identical daughter cells.

Question 3

What is the term for movement of water from an area of lower solute concentration to an area of higher solute concentration?

Accepted Answer

Osmosis is the process by which water moves across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Question 4

What are the distinct surface proteins of the plasma membrane essential in determining?

Accepted Answer

Distinct surface proteins of the plasma membrane are essential in determining tissue typing, as they play a crucial role in the immune response and compatibility in organ transplants.

Question 5

How are the thoracic and abdominal cavities separated?

Accepted Answer

The diaphragm is a muscular sheet that separates the thoracic cavity from the abdominal cavity, playing a crucial role in respiration.

Question 6

What traits describe visceral muscles?

Accepted Answer

Visceral muscles, also known as smooth muscles, are found in the walls of internal organs such as the stomach, intestines, and blood vessels. They are involuntary, meaning they function without conscious control.

Question 7

____ explains the processes and functions of many structures of the body and how they interact with one another.

Accepted Answer

Physiology is the branch of biology that explains the processes and functions of various structures of the body and how they interact with one another. It focuses on the mechanisms of the body's functioning, contrasting with anatomy, which deals with the structure of body parts.

Question 8

What does the transverse body plane divide?

Accepted Answer

The transverse body plane, also known as the horizontal plane, divides the body into superior (upper) and inferior (lower) portions.

Question 9

What is the broad section of biology dealing with the description of human structure?

Accepted Answer

Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts, including human structure.

Question 10

When several organs and parts are grouped together for certain functions,they form:

Accepted Answer

When several organs and parts are grouped together for certain functions, they form systems. This is a fundamental concept in biology where different organs work together to perform complex functions, such as the digestive system or the respiratory system.

Question 11

When the patient complains of pain in the bladder,the patient will indicate discomfort in which body cavity?

Accepted Answer

The bladder is located in the pelvic cavity, which is the lower part of the abdomen situated between the pelvic bones.

Question 12

Caudal is defined as toward the ____.

Accepted Answer

Caudal refers to a direction towards the tail or posterior part of the body, opposite of the head.

Question 13

The nurse is aware that which muscle group is both striated and involuntary?

Accepted Answer

Cardiac muscle is both striated and involuntary, meaning it has a banded appearance and operates without conscious control, primarily found in the heart.

Question 14

The anatomic structure that is not in the thoracic cavity is/are the _____.

Accepted Answer

The transverse colon is part of the digestive system located in the abdominal cavity, not the thoracic cavity. The heart, lungs, and blood vessels are all located within the thoracic cavity.

Question 15

What are the smallest living components in our body?

Accepted Answer

Cells are the smallest living components in our body, serving as the basic building blocks of all life forms.

Question 16

The anatomic term ____ means toward the midline.

Accepted Answer

The term "medial" is used in anatomy to describe a position closer to the midline of the body.

Question 17

What is the type of tissue composed of cells that contract in response to a message from the brain or spinal cord?

Accepted Answer

Muscle tissue is specialized to contract in response to stimulation, a function that is essential for movement and is controlled by signals from the brain or spinal cord.

Question 18

In anatomic terminology,posterior means toward the:

Accepted Answer

Posterior in anatomical terminology refers to the direction towards the back side of the body.

Question 19

Telophase is which phase of cell reproduction during mitosis?

Accepted Answer

Telophase is the final phase of cell reproduction during mitosis, where the chromosomes de-condense, nuclear envelopes re-form around the separated daughter chromosomes, and the cell prepares to divide into two.

Question 20

What is a group of several different kinds of tissues arranged so that together they can perform a more complex function than any tissue alone?

Accepted Answer

An organ is a structure made up of different types of tissues that work together to perform a specific function, which is more complex than what any single type of tissue could do on its own.
