they are located in the limbs, because the limbs are the effectors of the withdrawal reflex.
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.
Muscle stretch receptors are sensory receptors located in muscles that detect changes in muscle length. When a muscle is stretched during physical activity, these receptors send signals to the brain, which helps the body sense and respond to the changes in muscle length. This information is important for maintaining balance, coordination, and muscle control during movement.
The reflex associated with the sensory stimulation of the pulmonary stretch receptors is known as the Hering-Breuer reflex. It is responsible for inhibiting inspiration to prevent overinflation of the lungs, promoting expiration and maintaining normal breathing patterns.
The function of the stretch receptors in regulating breathing is to reduce the respiratory rate.
propriocepters respond to the movement of the body. cerebellum is responsible for the subconcious movement of the skeletal muscles. the primary motor cortex is a cortical site involved with controlling movements of the body. movement is part voluntary control.
Free dendritic endings do not belong as they are a type of nerve ending located in connective tissue that detects pain and temperature changes, whereas the other options are types of cutaneous receptors that detect touch, stretch, and pain.
The sensory receptors that detect change are called mechanoreceptors. These receptors are sensitive to mechanical stimuli such as pressure, vibration, and stretch, allowing the body to detect changes in its environment. Examples of mechanoreceptors include Pacinian corpuscles and Merkel cells.
Stretch receptors in the bladder wall send signals to the central nervous system when the bladder is full. These receptors detect the stretching of the bladder as it fills up with urine, triggering the sensation of needing to urinate.

receptor: initiate impulse: receive something sensory neuron: will carry impulse from receptors to the central nervous system motor neuron: tranmits impulse away from central nervous system into effector internuncial neuron: carry impulse from pre- synaptic to post synaptic effector: muscles or glands
