mechanoreceptor
Eyes: The sensory receptor in the eyes is the photoreceptor cell, specifically the rods and cones, which detect light and color. Nose: The sensory receptor in the nose is the olfactory receptor, located in the olfactory epithelium, which detects odor molecules. Tongue: The sensory receptors in the tongue are taste buds, which contain taste receptor cells that detect different tastes like sweet, salty, bitter, sour, and umami. Skin: The sensory receptors in the skin include mechanoreceptors (detect touch and pressure), thermoreceptors (detect temperature), nociceptors (detect pain), and proprioceptors (detect body position and movement).
Photoreceptors are the sensory receptors that allow detection of light and vision. They are located in the retina of the eye and are responsible for capturing light and converting it into electrical signals that the brain interprets as images.

Higher receptor densities may lead to more sensitive detection of stimuli and a more refined discrimination of sensory inputs in the receptive field. Lower receptor densities may result in decreased sensitivity and a broader receptive field. Additionally, differences in receptor densities can influence the spatial resolution and acuity of sensory systems.
The sensory receptor for static equilibrium is the vestibule located in the inner ear. The vestibule contains two structures called the utricle and saccule, which detect changes in head position and orientation to help maintain balance.
Mechanoreceptors are sensory receptors that respond to the distortion or bending of tissue. They are responsible for detecting touch, pressure, vibration, and proprioception.
Mechanoreceptors
Yes the sensory receptor is the first element.
Sensory receptor located at the distal end of a neuron or an associated sensory structure. When stimulated it creates a receptor potential, when that reaches its threshold, it will trigger 1 or more nerve impulses in the sensory neuron.
The first order sensory neuron can sometimes be a sensory receptor because it is what sends the signal to the brain from the receptor. The second order goes from the brainstem to the thalamus.

The sensory receptor for smell is called the olfactory receptor. These receptors are located in the olfactory epithelium in the upper part of the nasal cavity and are responsible for detecting and transmitting odors to the brain for interpretation.
Sensory receptor cells
Sensory receptor cells
Adaptation of nerve cells in simple sensory receptors can be seen in how they respond differently to constant stimuli over time. For example, in a pressure receptor in the skin, the nerve cells may initially fire rapidly in response to pressure but then slow down as they adapt to the constant pressure stimulus.
The sensory receptor for the eyes is the photoreceptor cells located in the retina. There are two main types of photoreceptors: rods, which are sensitive to low light levels and help with night vision, and cones, which are responsible for color vision in bright light.
Tactile cells are specialized cells found in the skin that help detect touch sensations. They are responsible for transmitting information about pressure, vibrations, and texture to the brain through the nervous system.
