Example Questions

Example Question #51 : Types Of Cells And Tissues

Where in the human body can skeletal muscle tissue be found?

Possible Answers:

Anchored to bones by tendons

In the heart 

In the walls of organs

None of these

Correct answer:

Anchored to bones by tendons

Explanation:

Skeletal muscle tissue is one of three types of muscle tissue. Skeletal muscle, as the name implies, is anchored to bones by tendons and controls skeletal movement and posture.

Example Question #52 : Types Of Cells And Tissues

Where in the human body can smooth muscle tissue be found?

Possible Answers:

The walls of organs

Only in the heart

Within bone marrow 

Anchored to bones

Correct answer:

The walls of organs

Explanation:

Smooth muscle tissue is a categorization of muscle tissue that is involved in involuntary contractions. Smooth muscle tissue can be found within the walls of organs such as the bladder, intestines, and stomach.

Example Question #53 : Types Of Cells And Tissues

Which of the following is true regarding the structure of smooth muscle tissue?

Possible Answers:

It is not striated 

It is bundled by connective tissue 

All of these

None of these

Correct answer:

All of these

Explanation:

Smooth muscle tissue is involved in involuntary contractions. This type of muscle tissue is not striated and is bundled by connective tissue.

Example Question #51 : Types Of Cells And Tissues

Smooth muscle tissue performs which of the following types of muscle contractions?

Possible Answers:

The mechanism and function of contraction is different in every organ

Involuntary

Contractions do not involve myosin and actin

Voluntary

Correct answer:

Involuntary

Explanation:

In smooth muscle tissue, contraction is involuntary and is caused by the sliding of actin and myosin filaments over one another. The function and mechanics of these contractions are generally the same in every organ; however, the physiological impact of each contraction may differ.

Example Question #21 : Understanding Muscle Cells

Which of the following types of muscle tissue is only found in the heart?

Possible Answers:

Smooth

Cardiac

Skeletal

Both cardiac and smooth

Correct answer:

Cardiac

Explanation:

Cardiac muscle tissue is only found in the heart.

Example Question #52 : Types Of Cells And Tissues

Which of the following does not describe the structure of cardiac muscle tissue?

Possible Answers:

Intercalated disks connect cardiomyocytes

It is not striated

It is striated

Each cell has one nucleus

Correct answer:

It is not striated

Explanation:

Cardiac muscle tissue is a type of striated muscle tissue that is complex and interconnected. Cardiomyocytes are connected end-to-end by intercalated disks. This allows for quick transmission of electrical signals. Cardiomyocytes have one nucleus each.

Example Question #53 : Types Of Cells And Tissues

Which of the following best describes cardiac muscle tissue contractions?

Possible Answers:

Contraction propels blood out of the atria and ventricles

All of these

Contractions are rhythmic and continue for the entire life of a human being

Contractions are involuntary 

Correct answer:

All of these

Explanation:

Cardiac muscle tissue is located only in the heart and contractions in this type of tissue are critical in propelling blood through the circulatory system. Contraction is involuntary, rhythmic, and continues through the entire life of a human.

Example Question #58 : Types Of Cells And Tissues

Which of the following is true regarding all type II skeletal muscle tissues?

Possible Answers:

They are fast twitch muscles

They are aerobic 

They are anaerobic

They are "white" muscles

Correct answer:

They are fast twitch muscles

Explanation:

Type II skeletal muscle tissues are all fast twitch muscles, but vary in their use of oxygen.

Example Question #54 : Types Of Cells And Tissues

Which of the following is not a feature of type I skeletal muscle tissue?

Possible Answers:

It has many mitochondria

It is "red" muscle tissue

It is classified as fast twitch muscle tissue

It is involved in aerobic activities

Correct answer:

It is classified as fast twitch muscle tissue

Explanation:

Type I skeletal muscle tissue is a red—oxygenated—muscle tissue that carries oxygen and is involved in aerobic activity. As a result, type I tissue is a slow twitch muscle. Type I skeletal muscle tissue contains many mitochondria.

Example Question #55 : Types Of Cells And Tissues

Which of the following best represent characteristics of type IIa skeletal muscle tissues?

Possible Answers:

They feature aerobic activity

They don't have many mitochondria and are anaerobic

They contain many mitochondria

They are both aerobic and contain many mitochondria

Correct answer:

They are both aerobic and contain many mitochondria

Explanation:

Type IIa skeletal muscle tissue is a subtype of skeletal muscle tissue that is related to fast twitch muscles. Type IIa tissues are aerobic and have many mitochondria.
