• Cells, tissues, organs, organ systems, chemical, body

• Chemical, cells, tissues, organs, organ systems, body

• Tissues, cells, organs, chemical, organ systems, body

• Chemical, tissues, cells, organs, organ systems, body

Which primary tissue type is primarily responsible for covering and protecting body cavities and organs?

• Nervous tissue

• Muscle tissue

• Epithelial tissue

• Connective tissue

Who is credited with being the first to make and use truly high-power microscopes, leading to the observation of microorganisms and earning the title "Father of Microbiology"?

• Hans and Zacharias Jansen

• Robert Hooke

• Anton van Leeuwenhoek

• Joseph von Gerlach

What was the key accidental discovery made by Joseph von Gerlach that allowed for the successful staining of brain cells and the visualization of neural fibers?

• Using a dye derived from saffron.

• Applying a highly concentrated carmine solution.

• Employing a long, slow soak in a diluted carmine solution.

• Heating the tissue sample before applying the stain.

What are the primary functions of nervous tissue?

• Contracting and moving the body.

• Providing support and insulation to other tissues.

• Sensing stimuli and transmitting electrical impulses.

• Lining organs and forming protective barriers.

Which part of a neuron is primarily responsible for receiving signals from other cells?

• Axon

• Cell body (soma)

• Dendrites

• Nucleus

Which of the following accurately describes cardiac muscle tissue?

• It is voluntary, multinucleate, and found attached to bones.

• It is involuntary, striated, and contains intercalated disks.

• It is involuntary, non-striated, and lines hollow organs.

• It is voluntary, uninucleate, and forms tight-knit sheets.

What is a distinguishing characteristic of smooth muscle tissue?

• It is responsible for voluntary movements.

• Its cells are long, cylindrical, and multinucleate.

• It lacks striations and is found in the walls of internal organs.

• It contains intercalated disks for rapid signal transmission.
