Tissue types epithelial muscle nerve flashcards

What is epithelial tissue?

A tissue that covers body surfaces and lines cavities. It consists of closely packed cells with minimal extracellular matrix.

Function of muscle tissue?

Responsible for movement. Types include skeletal (voluntary), smooth (involuntary), and cardiac (heart).

True or false: Nerve tissue initiates movement.

False, because nerve tissue transmits impulses and processes information.

Difference between skeletal and smooth muscle?

Skeletal muscle is voluntary and striated, while smooth muscle is involuntary and non-striated.

Fill in the blank: Epithelial tissue is classified by ____ and number of layers.

shape (squamous, cuboidal, columnar)

What is the main function of nerve tissue?

To transmit electrical signals throughout the body, facilitating communication between different parts.

Example of connective tissue?

Blood, bone, adipose (fat), and cartilage are types of connective tissue.

What does cardiac muscle do?

Contracts involuntarily to pump blood throughout the body. Found only in the heart.

True or false: Epithelial cells can regenerate.

True, because they have a high capacity to divide and repair quickly.

Comparison of central and peripheral nervous system

Central includes brain and spinal cord; peripheral consists of nerves outside the CNS.

What type of epithelial tissue is found in the lungs?

Simple squamous epithelium facilitates gas exchange due to its thinness.

Function of adipose tissue?

Stores energy, provides insulation, and cushions organs.

Identify this type: voluntary, striated muscle.

Skeletal muscle.

Fill in the blank: Smooth muscle is found in ____ organs.

hollow organs like the intestines and blood vessels.

True or false: All muscle tissues have striations.

False, because smooth muscle does not have striations.

What is the role of neuroglia?

Support and protect neurons, maintaining homeostasis and insulating them.
