THE SENSES 2 Flashcards
Somatosensation (NEXT LEVEL)
information gathered by The skin, muscles, and joints
receptors that can sense touch, pressure,
temperature, pain, or the position of the body
HOW MANY STIMULUS TYPES CAN 1 RECEPTOR CELL RESP0ND TO?
1
Mechanoreceptors
nerve endings that are encapsulated by connective tissue that
sense touch and pressure.
HOW MANY TYPES OF encapsulated nerve endings ARE THERE
3 WITH 3 DIFFERENT MORPHOLOGIES
WHAT DOES THE Stretching of the connective tissue fibers of the encapsulated endings DO?
activates ion
channels which can produce action potentials that signal to the central nervous system
How are Posture and movement of body parts sensed?
by muscle stretch
mechanoreceptors, as well as mechanoreceptors present in skin, joints, tendons, and
ligaments. They sense the amount of muscle stretch as well as the rate of muscle stretch.
proprioception
the perception of where the body is in space, by Vision and balance
thermoreceptors
sense temperature
how is temperature sensed?
Free nerve endings, which are processes of neurons, sense temperature using ion
channels that are activated only at certain temperatures
nociceptors
sense pain, extreme mechanical deformation, high temperatures, as well as chemicals released by damaged cells or immune cells.
