The primary cells found in the epidermis, making up about 90% of epidermal cells.

The outermost layer of the skin, composed of closely packed epithelial cells (keratinocytes).

The deepest layer of the epidermis, made up of actively dividing cells.

The outermost layer of the epidermis, composed of dead skin cells.

A layer of the epidermis found only in thick skin areas like palms and soles.

A layer of the epidermis that provides a water-proof barrier to prevent fluid loss.

A layer in the epidermis with 8-10 cell layers.

Protection from damage by environment, pathogenic microorganisms, and water loss; sensation; temperature regulation; vitamin D synthesis; excretion.

8-10 layers of keratinocytes connected by desmosomes and pre-keratin microfilaments.

Cells in this layer resemble miniature pincushions.

Specialized immune cells that defend against germs and skin cancers.

Connect cells to the basal lamina, separating epidermis from the dermis.

Skin pigment-producing cells, making up 10-25% of the epidermis.

Top layer of the dermis, made of areolar tissue, containing vessels and sensory neurons.

Lower dermis layer, thick, made of dense irregular tissue, resists stretching, contains collagen & elastic fibers.

Pigment produced by melanocytes, giving skin its color.

Orange-yellow pigment from plants, found in skin and fatty tissues.

Inherited condition resulting in very light skin, hair and eyes due to low melanin.

The varying coloration of skin, influenced by melanin and other pigments.

Finger-like projections of the dermis that interlock with epidermal ridges, increasing surface area contact.

The sense of taste, which allows us to detect flavors in food and drinks.

Sweet, salty, sour, and bitter are the four fundamental taste sensations detected by our taste buds.

Structures on the tongue that contain gustatory cells responsible for detecting taste.

The sense of smell, which involves detecting odor molecules in the air.

Specialized cells in the nasal cavity that detect odor molecules and send signals to the brain.

The sense of hearing, which involves converting sound waves into neural signals.

A thin membrane in the ear that vibrates in response to sound waves.

Three small bones in the middle ear that transmit vibrations from the tympanic membrane to the oval window.

Sweat glands (also called sudoriferous glands) are responsible for producing sweat, which helps regulate body temperature.

Eccrine sweat glands are found all over the body and play a crucial role in thermoregulation. They release a watery sweat that helps cool the body.

Apocrine sweat glands are located in areas with hair, like armpits and genitalia. Their sweat is thicker and contains organic compounds, which can lead to body odor when bacteria break it down.

Sebaceous glands are oil glands found all over the body, especially associated with hair follicles. They produce sebum, a mixture of lipids that lubricates skin, waterproofs hair, and has antibacterial properties.

Sebum, produced by sebaceous glands, helps lubricate skin and hair, waterproofs hair, and has antibacterial properties to prevent water loss and protect against infections.

Thermoregulation is the process of maintaining a stable body temperature. The skin plays a crucial role in this process by regulating blood flow and sweat production.

The skin regulates blood flow to the surface, widening blood vessels for heat loss and narrowing them for heat retention. Sweat evaporation also helps to cool the body down.

The size of a burn is a critical factor in determining the severity and treatment required. Specific body areas are associated with a percentage of the total body surface area.

The Eustachian tube equalizes pressure in the middle ear with external air pressure during activities like swallowing, yawning, or the Valsalva maneuver.

The Eustachian tube, connecting the middle ear to the back of the throat, is composed of both bone and cartilage.

Sound travels through the external auditory canal, reaches the eardrum (tympanic membrane), vibrates ossicles, transmits to the oval window, moves fluid in the cochlea, activating hair cells, and finally reaches the cochlear nerve.

The cochlea, part of the inner ear, houses the organ of Corti, responsible for converting sound vibrations into electrical signals that the brain interprets.

The vestibular system in the inner ear, including the utricle and saccule, plays a vital role in maintaining balance and equilibrium.

The inner ear encodes information about equilibrium, the sense of balance, using specialized hair cells called mechanoreceptors.

Fluid movement within the semicircular canals of the inner ear, triggered by head movement, bends hair cells that relay information about head position to the brain.

The organ of Corti is located within the cochlea of the inner ear, where it plays a crucial role in sound transduction.
