This chapter introduces the concept of the sensory nervous system and briefly discusses the value of model organisms in enhancing our understanding of the evolution of sensory systems. Introduction.
The sensory system translates light, sound, temperature, and other aspects of the environment to electrical signals and transmits these signals, in the form of Action Potentials, to the Central Nervous System, where they are Interpreted. Thus, the functions of receptors of sensory systems are due to their structure and location in the sense organs. answer choices. There are three muscle types; smooth, cardiac and skeletal muscles. Sensory Systems. Posterior: Dorsal column tracts: propriception, vibration, light tough; Lateral: Lateral spinothalamic tract: pain and temperature; Posterior spinocerebellar tract: tendon and joint position; Anterior spinocerebellar tract: tendon and joint position light pressure. All of the above are stimuli touch receptors respond to. The nervous system has three overlapping functions; sensory input, integration, and motor output.

The organs of the sensory system are the eyes, ears, tongue, nose, and skin.
Spinal sensory nerves carrying signals from receptors to the sensory cortex have a particular arrangement in the spinal cord.
The five basic sensory systems: 1. First, the primary function of the nervous system is to collect sensory information from the environment. Ch. Commonly recognized sensory systems are those for vision, hearing, somatic sensation (touch), taste and olfaction (smell). The receptors could be classified into two parts viz.
There are 3 functions of the nervous system. There have been numerous scoring systems suggested that includes asking the patient to grade the sensation on a scale of 1 to 10 or 1 to 100. This is a sensory pathway carrying pain, temperature, touch, and pressure sensations. The sensation you experience, also called a stimulus, is captured by sensory receptors, which receive the stimulus and convert them into nerve impulses that travel all the way through sensory nerves to the brain for interpretation.
