the pathways of the spinal cord that carry information from the peripheral nervous system (pns) to the brain, carry only ____ information a. muscle stimulation b. gross body movement c. all of the above d. sensory

Transcript

00:01 Today we're going to briefly look at the sensory system.

00:04 The sensor system detects stimuli such as light and sound waves and transcuse them into neural signals that can be interpreted by the nervous system, specifically the central nervous system.

00:25 In addition to the external stimuli i just talked about, there are some sensory systems also detect internal stimuli, such as proprioceptors in muscles and tendons that send feedback about the limb position.

00:42 Sensory systems include visual, auditory, gustatory, and somatosensory systems.

01:19 So visual being vision, being able to see things, auditory being able to hear, gustatory being taste, alfactory being smell, and somatosensory being touch, pain, temperature, proporeception, etc.

01:35 I forgot to mention one more.

01:38 Final one here.

01:43 This is stilule, which is balance and spatial orientation, for example.

01:49 There are five general properties of the sensory system, which i think are worth knowing.

01:54 Receptors are sensitive to center of warmth of energy.

01:57 Two, sensory transduction convert stimuli to great potentials.

02:02 Three, sensory neurons have receptive fields, and receptive fields are just a region of space in which a presence of stimuli.

02:09 Will alter the firing of sensory neuron.

02:12 4.

02:12 The central nervous system integrate sensory information.

02:16 And 5...
