What are the four characteristics that make muscle tissue different from other tissues?
What are the four characteristics that make muscle tissue different from other tissues?
The four characteristics of muscle tissue are excitability, contractility, extensibility, and elasticity.
What is the role of a motor neuron in stimulating a muscle cell?
What is the role of a motor neuron in stimulating a muscle cell?
A motor neuron is responsible for stimulating a muscle cell by releasing specific neurotransmitters that trigger a response in the muscle cell.
Explain the concept of excitability in muscle tissue.
Explain the concept of excitability in muscle tissue.
Excitability refers to the ability of muscle tissue to respond to stimuli, particularly from motor neurons, by generating electrical impulses and initiating muscle contractions.

Study Notes
Characteristics of Muscles
- Muscles have four unique characteristics that distinguish them from other tissues
- One of these characteristics is excitability, meaning muscle cells can be stimulated by motor neurons
Muscle Stimulation
- A motor neuron releases a signal that stimulates a muscle cell to contract
- This process requires the motor neuron to release a specific signal to the muscle cell
Circulatory System
Overview
- The circulatory system, also known as the cardiovascular system, consists of the heart, blood vessels, and blood
- It is a closed system in vertebrates, meaning the blood never leaves the network of blood vessels
Components
- The circulatory system has two divisions: systemic circulation and pulmonary circulation
- It includes the heart, large elastic arteries, smaller arterioles, capillaries, venules, and veins
Comparison to Invertebrates
- Some invertebrates, such as arthropods, have an open circulatory system, unlike vertebrates
