Epidermis, cornea, various connective tissues

Feeling the stimulation of temperature, stress and certain chemical substances, producing hot and cold, light touch and pain sensations

Dermal papillae, most common on fingers

produce tactile sensation

subcutaneous tissue, peritoneum, mesentery, ligaments and joint capsules

Pressure and vibration sensation

skeletal muscle

Proprioceptors play an important role in regulating skeletal muscle activity

skeletal muscle

The axon branches repeatedly, and each branch forms a grape-like terminal and establishes a synaptic connection with the skeletal muscle. This connection area is an oval plate-like bulge.

innervates skeletal muscles

A motor neuron and all the skeletal muscle fibers it innervates

Myocardial viscera and vascular smooth muscle, glands

Controls and regulates muscle cell contraction and gland secretion
