Nervous Tissue Flashcards

Questions and Answers

What is the main function in the nervous tissue found in the human body?

Nervous tissue is found in the brain, spinal cord, and nerves, and plays a major role in emotions, memory, and reasoning.

What primary organ of the human body is mostly made up of the nervous tissue?

The central nervous system is made up of the brain and spinal cord.

Describe what the cells in the nervous tissue look like.

How does the nervous tissue work, with the other tissues that make up the organ, to make this organ work?

Cells make up tissues, tissues make up organs, and organs make up organ systems. All the systems of the body work together to keep an organism up and running. The neurons are the basic functional unit of the nervous system. Signup and view all the answers

What is the main function of the muscle tissue found in the human body?

Skeletal muscle fibers are cylindrical, multinucleated, striated. Smooth muscle cells are spindle-shaped, have a single, centrally located nucleus, and lack striations. Signup and view all the answers

How does the muscle tissue work, with the other tissues that make up the organs, to make this organ work?

There are many different types of cells, but all have the same basic structure. Tissues are layers of similar cells that perform a specific function. The different kinds of tissues group together to form organs. Signup and view all the answers

Study Notes

Nervous Tissue

Main function involves emotions, memory, and reasoning, primarily located in the brain, spinal cord, and nerves.
Central nervous system comprises the brain and spinal cord.
Neurons serve as the basic functional unit of the nervous system, facilitating communication between different parts of the body.
The human brain contains more nerve cells than there are stars in the Milky Way, with approximately 100 billion neurons.
If all neurons in the body were lined up, they would measure around 965 km in length.
A newborn's brain grows almost three times in size during its first year.

Muscle Tissue

Skeletal muscle fibers are cylindrical, multinucleated, and striated, while smooth muscle cells are spindle-shaped with a single nucleus and lacking striations.
The muscular system, consisting of around 700 named muscles, enables body movement and constitutes about half of an individual's body weight.
Muscles account for approximately 40% of total body weight; the heart is the most active muscle.
The gluteus maximus is identified as the largest muscle in the body, while the smallest muscles are found in the ear alongside the smallest bones.
Skeletal muscles are unique as they can be consciously controlled.

Connective Tissue

Key functions include binding and supporting other tissues, protecting organs, insulating, storing energy, and transporting substances.
Connective tissues are prevalent throughout the body, particularly abundant in organs like the liver and spleen.
This tissue type effectively supports and connects various other tissues and organs, establishing structural integrity.

Epithelial Tissue

Epithelial cells form layers that lack blood vessels, receiving nourishment through diffusion from underlying connective tissues.
This type of tissue includes organs and structures that line surfaces of the body and hollow organs.
Loose connective tissue is commonly associated with epithelial tissues, providing support and attachment to underlying structures.
