Identify the major layers of the skin

Using the Skin Layers knowledge point, we identify the three primary regions of the integument on the right side of the diagram:

• The upper bracket spans the entire epithelial layer, which is the Epidermis.
• The middle bracket spans the thick connective tissue layer beneath the epidermis, which is the Dermis.
• The lower bracket points to the subcutaneous layer containing adipose tissue, which is the Hypodermis.

Identify the epidermal strata

Using the Epidermal Strata knowledge point, we identify the specific layers of the epidermis pointed to on the left side:

• The topmost target points to the outer, keratinized layer of the epidermis: Stratum corneum.
• The second target down points to the intermediate layer of the epidermis: Stratum spinosum.
• The third target down points to the deepest, single-cell layer of the epidermis: Stratum basale.

Identify dermal structures and glands

Using the Integumentary System Anatomy knowledge point, we identify the remaining structures on the left side:

• The fourth target down points to the finger-like projections of the dermis extending into the epidermis: Dermal papillae.
• The fifth target down points to the opening of the sweat gland duct at the skin surface: Sweat pore.
• The sixth target down points to the yellow, branching nerve endings in the dermis: Sensory neurons.
• The seventh target down points to the coiled tubular gland in the dermis: Sweat gland.

<answer>
The correct labels for the targets in the diagram, from top to bottom for each column, are:

Left Column (Top to Bottom):

1. Stratum corneum (points to the outermost layer of the epidermis)
2. Stratum spinosum (points to the middle layer of the epidermis)
3. Stratum basale (points to the deepest layer of the epidermis)
4. Dermal papillae (points to the dermal ridges projecting upward)
5. Sweat pore (points to the opening of the sweat duct at the surface)
6. Sensory neurons (points to the yellow nerve fibers in the dermis)
7. Sweat gland (points to the coiled secretory portion in the dermis)

Right Column (Top to Bottom):

1. Epidermis (bracket spanning the entire epithelial layer)
2. Dermis (bracket spanning the thick connective tissue layer)
3. Hypodermis (bracket spanning the subcutaneous layer at the bottom)
