Final answer:
Hearing, seeing, smelling, and detecting motion are examples of sensory modalities, which are part of the nervous system's ability to receive and interpret sensory information from our environment.
Step-by-step explanation:
Hearing, seeing, smelling, and detecting motion are all functions associated with sensory modalities, which are a part of the nervous system functions. The five main senses through which these modalities operate are hearing, sight, taste, touch, and smell. Our sensory organs contain special cells called sensory receptors that respond to specific types of stimuli. When these receptors are stimulated, they send nerve impulses via sensory nerves to the central nervous system, where the brain interprets these impulses, allowing us to perceive our environment.
The process by which a stimulus is converted into an electrical signal in the nervous system is known as sensory transduction. This is a fundamental function of the sensory systems, regardless of whether the stimulus comes from the external environment, like light or sound, or from the internal environment of the body, such as the position or movement of limbs, which is part of somatosensation.
