Pacini/lamellated corpuscle
Encapsulated:
Pacini/lamellated corpuscle
Dermis, fingers, breasts, genitalia, viscera Dendrites shielded in concentric cell layers Large, ca. 1mm long
Deep pressure, vibration and pulsing
Fast adaptation
Proprioceptors
Monitor the position of joints, tendons, ligaments, muscles
Integrated with vestibular system information
Muscle spindles: muscle length
Golgi organs: tendon tension
Free nerve endings: joint tension,
Pressure, movement, stretching
Anterior spinothalamic tract
Lateral spinothalamic tract
Posterior column
Pressure - Baroreceptors
Stretch receptors in organ walls
Free nerve endings branching within an elastic wall of a hollow organ
Stretching distorts dendritic branches
Alteration of action-potential generation
Fungiform papillae
Fungiform papillae: ca. 5 taste buds
Circumvallate papillae
Circumvallate papillae: ca 100 taste buds
Filiform papillae
Filiform papillae: no taste buds
