no, only the dermis is propogated with nerve endings
No, the outermost layer of skin, known as the epidermis, is not composed entirely of hair receptors. Instead, it consists primarily of keratinocytes, which provide a protective barrier, along with various other cells, including melanocytes and Langerhans cells. Hair receptors, or hair follicle receptors, are specialized nerve endings associated with hair follicles that respond to movement and touch, but they are not the predominant component of the epidermis.
Free nerve endings functions as cutaneous receptors ( is a sensory receptor present on dermis or epidermis ). Present in vertebrates for sense of pain. they are frequently found on skin. *Muscle spindles
Merkel cells are found in the basal layer of the epidermis and function as mechanoreceptors responsible for detecting light touch and pressure on the skin. These specialized cells are connected to sensory nerve endings and play a role in sensory perception.
There are about 17,000 touch receptors or nerve endings in a human hand, making it one of the most sensitive parts of the body. These nerve endings help us feel sensations such as pressure, temperature, and pain, allowing us to interact with our environment.
tactile (Merkel) discs
Cutaneous receptors for pain are located primarily in the skin and subcutaneous tissue. They are particularly concentrated in the outermost layer of the skin, known as the epidermis, and in the underlying dermis. These receptors are responsible for detecting painful stimuli such as heat, pressure, or injury on the skin's surface.
no, only the dermis is propogated with nerve endings
The dermis layer of the skin is composed of thousands of sensory receptors, including touch receptors, temperature receptors, and pain receptors. These receptors help you to feel sensations and respond to your environment.
The epidermis does not but the lower layers of the dermis do.

Thermoreceptors
Temperature receptors in the human body are located in the skin, especially in the dermis and epidermis layers. These receptors help to detect changes in temperature and send signals to the brain to regulate body temperature. Temperature receptors are also present in internal organs to help maintain internal temperature balance.
Sensory receptors in the dermis include: free nerve endings, pacinian corpuscles, and hair follicle receptors The mechanoreceptors of the skin are the meissner's corpuscles (which respond to light touch), the pacinian corpuscles (deeper in the dermis and respond to pressure), and the merkel's disks (closely related to the merkel's cells located in the epidermis and respond to light touch). The nociceptors are pain receptors that recognize hot, cold, and pain.
