1What is the primary role of nervous tissue in the body?
Forming a widespread network of communication with numerous connections.
2How many main systems does the nervous tissue consist of?
Two main systems: the central nervous system (CNS) and the peripheral nervous system (PNS).
3What are the two main types of cells within the nervous tissue?
Neurons and glial cells.
4What are neurons responsible for?
Receiving, processing, storing, and transmitting information.
5What are the three key properties of neurons?
Excitability, conductivity, and communicability.
6How do neurons organize and coordinate the functions of the body?
Through their properties of excitability, conductivity, and communicability.
7Besides transmitting information, what additional function do neurons have?
They have an endocrine function, contributing to hormonal regulation.
8What are glial cells also known as?
Neuroglial cells.
9What role do glial cells play in the nervous system?
They play a supportive role, protecting and nourishing neurons, regulating their activity, and defending the nervous system.
10What is the collective function of neurons and glial cells?
Ensuring the proper functioning of the nervous system.
11What property allows neurons to respond to stimuli and generate electrical signals?
Excitability.
12What enables the transmission of electrical signals along the length of neurons?
Conductivity.
13How do neurons communicate with each other?
Through synaptic connections.
14What is the primary role of the central nervous system (CNS)?
Integration and processing of sensory information.
15What is the primary role of the peripheral nervous system (PNS)?
Transmitting information to and from the CNS.
16What is the function of glial cells in regulating neuronal activity?
They regulate the environment around neurons and modulate synaptic transmission.
17How do glial cells contribute to the nervous system?
By protecting and nourishing neurons, as well as defending the nervous system.
18What ensures the proper functioning of the nervous system?
The complex network formed by neurons and glial cells.
19What allows for the transmission of signals and the coordination of bodily functions in the nervous system?
The proper functioning of neurons and glial cells.
20What are the two main divisions of the nervous tissue?
The central nervous system (CNS) and the peripheral nervous system (PNS).
