1.
This tissue has cells that are packed tightly together.
Correct Answer
C. Epithelial
Explanation
Epithelial tissue is composed of cells that are tightly packed together, forming a continuous layer. This type of tissue is found in the lining of organs, blood vessels, and body cavities. Its main function is to protect underlying tissues, regulate the exchange of substances, and provide a barrier against pathogens.
2.
This tissue includes: inner layers of the skin, tendons, ligaments, cartilage, bone, and fat tissue.
Correct Answer
B. Connective
Explanation
Connective tissue is the correct answer because it is the type of tissue that includes the inner layers of the skin, tendons, ligaments, cartilage, bone, and fat tissue. Connective tissue provides support and structure to the body, connects different tissues and organs, and helps in the transportation of nutrients and waste products. It is characterized by cells scattered within an extracellular matrix composed of fibers and ground substance.
3.
I support and give structure to the body.
Correct Answer
B. Connective
Explanation
Connective tissue is the correct answer because it supports and gives structure to the body. Connective tissue is found throughout the body and is responsible for connecting, supporting, and protecting other tissues and organs. It provides strength and elasticity to different parts of the body, such as tendons, ligaments, and bones. Connective tissue also plays a role in immune responses and the transport of nutrients and waste products. Overall, connective tissue is essential for maintaining the structural integrity and functionality of the body.
4.
I contain both neurons and glial cells.
Correct Answer
C. Nerve
Explanation
The correct answer is "Nerve" because nerves are composed of both neurons and glial cells. Neurons are responsible for transmitting signals, while glial cells provide support and protection to the neurons. Therefore, nerves are the only option that contains both neurons and glial cells.
5.
I allow movement in the body to occur.
Correct Answer
A. Muscle
Explanation
Muscles are responsible for allowing movement in the body. They are made up of specialized cells that contract and relax to produce movement. Muscles are attached to bones and work together with the skeletal system to enable various movements such as walking, running, and lifting objects. They are found throughout the body and are classified into three types: skeletal muscles, smooth muscles, and cardiac muscles. Skeletal muscles are attached to bones and are responsible for voluntary movements, while smooth muscles are found in the walls of organs and blood vessels and are responsible for involuntary movements. Cardiac muscles are found in the heart and are responsible for pumping blood.
6.
I generate and conduct electrical signals in the body.
Correct Answer
C. Nerve
Explanation
Nerves are responsible for generating and conducting electrical signals in the body. They transmit information between the brain, spinal cord, and other parts of the body. Nerves play a crucial role in coordinating movement, sensing touch, pain, and temperature, as well as controlling various bodily functions.
7.
The epithelial helps to keep the body's organs _______________, ________________, and ________________.
Correct Answer
separate, in place, protected
in place, protected, in place
in place, separate, protected
protected, separate, in place
separated, protected, in place
Explanation
The correct answer is "separate, in place, protected". The epithelial tissue acts as a barrier, separating the body's organs and tissues from each other. It also helps to keep them in their proper place and protects them from damage or infection.
8.
Blood is not a form of connective tissue.
Correct Answer
B. False
Explanation
Blood is a form of connective tissue because it is made up of cells suspended in a liquid matrix called plasma. Connective tissue is characterized by its ability to connect and support different structures in the body, and blood fulfills this function by transporting oxygen, nutrients, hormones, and waste products throughout the body. Additionally, blood plays a crucial role in immune responses and clotting, further highlighting its connective tissue nature. Therefore, the statement that blood is not a form of connective tissue is incorrect.
9.
There are over _________ muscles in the body.
Correct Answer
600
six hundred
Explanation
There are 600 muscles in the body.
10.
Muscles keep the body's organs cool.
Correct Answer
B. False
Explanation
Muscles do not directly keep the body's organs cool. The primary function of muscles is to generate heat through contraction, which helps to maintain body temperature. The cooling of organs is primarily regulated by the circulatory system, which transports blood and regulates blood flow to different parts of the body, including the organs.
