Are the cells that transmit sensory messages called nerve cells or muscle cells?
The cells that transmit sensory messages are called nerve cells or neurons. Muscle cells, also known as myocytes, are responsible for contraction and movement.
What maintains the tension in a muscle spindle?
The tension in a muscle spindle is maintained by intrafusal muscle fibers, which are specialized muscle fibers within the spindle that are innervated by sensory nerve fibers. These sensory fibers detect changes in muscle length and transmit signals to the central nervous system to regulate muscle tone and coordination.
Why does the message go to the brain only after the reflex response has occurred?
The reflex response occurs via a direct pathway called the reflex arc that bypasses the brain, allowing for a rapid reaction to stimuli. Sensory neurons transmit signals to the spinal cord, where interneurons immediately relay the message to motor neurons, triggering a quick muscle response. The brain receives the sensory information afterward, allowing for conscious awareness of the event, but the reflex action happens first to ensure a swift response to potential threats or dangers. This mechanism prioritizes survival by minimizing response time.
What system consist of sensory and motor neurons associated with voluntary actions?
The somatic nervous system consists of sensory and motor neurons that are associated with voluntary actions. Sensory neurons transmit sensory information from the body to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles to initiate movement. This system allows for conscious control over skeletal muscle movement.
What are the sensory receptors used to monitor muscle tone?
Muscle spindles are sensory receptors that monitor muscle tone. They are located within the muscle belly and are sensitive to changes in muscle length and stretch, providing feedback to the central nervous system about the state of muscle contraction.

What neurons are involved in a reflex?
3 neurons are included in the reflex arc. They are: Afferent neurons (take the message to the spinal cord) (sensory) Association neurons (directs message to the efferent neuron and the brain) (report reflex to the brain) Efferent neurons (takes message to effector) (motor) Not all reflexes have interneurons.

What kind of tissue is the tongue?
You tongue is a muscle, but it also has sensory structures called taste buds that are located on it.
What kind of bond is used to transmit impulses between nerve and muscle cells?
The type of bond used to transmit impulses between nerve and muscle cells is a chemical bond called a neurotransmitter. Neurotransmitters are released from the nerve cells and bind to receptors on the muscle cells, triggering a response that leads to muscle contraction.
How does effector relate to reflex arc?
An effector is a part of the body (such as a muscle or gland) that carries out the response in a reflex arc. In a reflex arc, when a stimulus is detected by a sensory receptor, a message is sent via a sensory neuron to the spinal cord, where it is processed, and then a message is sent via a motor neuron to the effector causing a response.
What are the sensory receptors used to monitor muscle tone?
Muscle spindles are sensory receptors that monitor muscle tone. They are located within the muscle belly and are sensitive to changes in muscle length and stretch, providing feedback to the central nervous system about the state of muscle contraction.
What is the Sensory pattern of the skin for the axillary nerve?
Its sensory distribution is the skin overlying the deltoid muscle.
What is the pathway of an impulse in a reflex arc?
Sensory receptor, sensory neuron, interneuron, motor neuron, and muscle.
