Tissues

Which of the following is the correct order of the hierarchy of organization from the simplest to the most complex?

• Cellular, Chemical, Tissues, Organs, Organ Systems, The Body

• Chemical, Cellular, Tissues, Organs, Organ Systems, The Body

• Chemical, Tissues, Cellular, Organs, Organ Systems, The Body

• Chemical, Cellular, Organs, Tissues, Organ Systems, The Body

Answer explanation

The correct order of organization is Chemical, Cellular, Tissues, Organs, Organ Systems, The Body. This sequence starts from the simplest level (chemical) and progresses to the most complex (the body).

Which type of tissue is responsible for control and communication in the body?

• Muscle Tissue

• Epithelial Tissue

• Nervous Tissue

• Connective Tissue

Answer explanation

Nervous tissue is responsible for control and communication in the body, as it transmits signals between different parts of the body, coordinating responses and processing information.

What is the primary function of muscle tissues?

• Provide Support

• Movement

• Cover and Protect the Body

• Control and Communication

Answer explanation

The primary function of muscle tissues is movement. They contract and relax to enable various bodily movements, making this the correct choice over support, protection, or control.

Which type of tissue covers and protects the body?

• Connective Tissue

• Nervous Tissue

• Muscle Tissue

• Epithelial Tissue

Answer explanation

Epithelial tissue is the type that covers and protects the body, forming the outer layer of skin and lining internal organs. It serves as a barrier and plays a crucial role in protection and absorption.

What is the main function of connective tissues?

• Control and Communication

• Movement

• Provide Support

• Cover and Protect the Body

Answer explanation

Connective tissues primarily function to provide support to various structures in the body. They help maintain the shape and integrity of organs and tissues, making 'Provide Support' the correct choice.

What is the study of tissues called?

• Cytology

• Histology

• Pathology

• Physiology

Answer explanation

The study of tissues is called histology. It focuses on the structure and function of tissues, distinguishing it from cytology, which studies cells, and pathology, which examines disease processes.

Which of the following is part of the Central Nervous System?

• Brain and Spinal Cord

• Neurons

• Glial Cells

• Peripheral Nervous System

Answer explanation

The Central Nervous System (CNS) consists of the brain and spinal cord, which are responsible for processing and transmitting information. Neurons and glial cells are components of the nervous system, but not part of the CNS itself.

What is the primary function of neurons?

• Provide support and insulation

• Send signals throughout the body

• Tether blood cells to provide nutrients

• Protect the brain

Answer explanation

The primary function of neurons is to send signals throughout the body, facilitating communication between different parts of the nervous system. This is essential for coordinating bodily functions and responses.

Which cells provide support, insulation, and protection in the nervous tissue?

• Neurons

• Brain cells

• Glial Cells

• Spinal Cord cells

Answer explanation

Glial cells, also known as neuroglia, provide essential support, insulation, and protection for neurons in the nervous tissue, unlike neurons which are primarily responsible for transmitting signals.

What is the role of glial cells in relation to blood cells?

• They send signals to blood cells

• They tether blood cells to provide nutrients to the neuron

• They protect blood cells from damage

• They insulate blood cells

Answer explanation

Glial cells support neurons by tethering blood cells, ensuring they receive essential nutrients. This relationship is crucial for maintaining neuronal health and function.
