What does it mean that neurons are excitable and how does this property contribute to their function in the nervous system?
Neurons being excitable means they can generate electrical signals in response to stimuli. This property allows them to communicate with each other and transmit information throughout the nervous system. Excitability is essential for processes like sending signals between neurons, controlling muscle movement, and processing sensory information.
What else can I help you with?
What kind of cells are excitable?
Excitable cells, such as neurons and muscle cells, have the ability to generate electrical signals called action potentials in response to stimuli. These cells play a crucial role in transmitting signals within the nervous system and facilitating muscle contractions.
Does stress affect the nervous system?
Yes, stress can affect the nervous system by triggering the release of stress hormones like cortisol, which can impact brain function, nerve signaling, and overall nervous system function. Chronic stress can lead to conditions like anxiety, depression, and even contribute to neurodegenerative diseases.
What are the only two types of cells that have excitable membranes?
The only two types of cells that have excitable membranes are neurons and muscle cells. Neurons transmit electrical signals in the nervous system, while muscle cells generate electrical signals that lead to muscle contraction.
What are the characteristics of nervous tissue?
Nerve tissue consists of nerve cells, nerve fibers, dendrites, and neuroglia. It is packed closely together and most are strongly branching. Its function are to regulate and control body processes.
What is the primary unit of function in the nervous tissue?
The primary unit of function in nervous tissue is the neuron. Neurons are specialized cells that process and transmit information through electrical and chemical signals. They form complex networks that allow for communication within the nervous system.
Is nervous a tissue?
No, nervous is an adjective meaning sensitive or excitable.
What nervous system function contributes to thinking?
The nervous system functions do not form thoughts but it could contribute to them. Arousal, which is a nervous system function, could lead to desire.
What are the two excitable tissues?
Gap Junction
What is a word that means of a nervous origin?
In a general sense it can mean highly excitable; unnaturally uneasy.
What kind of cells are excitable?
Excitable cells, such as neurons and muscle cells, have the ability to generate electrical signals called action potentials in response to stimuli. These cells play a crucial role in transmitting signals within the nervous system and facilitating muscle contractions.
What are the two excitable tissue in human body?
The two excitable tissues in the human body are nervous tissue and muscle tissue. Nervous tissue is responsible for transmitting electrical signals throughout the body, facilitating communication between the brain and other body parts. Muscle tissue, which includes skeletal, cardiac, and smooth muscle, generates electrical impulses that lead to contraction and movement. Both tissues play crucial roles in the body's ability to respond to stimuli and maintain function.

Does stress affect the nervous system?
Yes, stress can affect the nervous system by triggering the release of stress hormones like cortisol, which can impact brain function, nerve signaling, and overall nervous system function. Chronic stress can lead to conditions like anxiety, depression, and even contribute to neurodegenerative diseases.
One function of the nervous system is to maintain?
One function of the nervous system is to maintain the entire body.
What does it mean when you have a fizzy horse?
When a horse is referred to as being fizzy it means they are nervous or very excitable. Some people suggest changing their diet to change their mood.
How does the nervous system subdivide by function?
While this is an extremely important function, the brain relies upon the peripheral nervous.
