Identify epidermal layers and structures

The diagram shows a 3D cross-section of human skin. Let's trace the pointers on the left side from top to bottom:

1. The first pointer at the very top left points to the opening of the sweat duct on the skin surface: Sweat pore.
2. The second pointer points to the outermost, thick keratinized layer of the epidermis: Stratum corneum.
3. The third pointer points to the middle layer of the epidermis: Stratum spinosum.
4. The fourth pointer points to the deepest, single-cell layer of the epidermis: Stratum basale.
5. The fifth pointer points to the finger-like projections of the dermis extending into the epidermis: Dermal papillae.
6. The sixth pointer points to the yellow nerve fibers in the dermis: Sensory neurons.
7. The seventh pointer points to the coiled tubular gland in the dermis: Sweat gland.
8. The eighth pointer at the bottom left points to the subcutaneous layer containing adipose tissue: Hypodermis.

Identify major skin regions

Now let's trace the brackets on the right side:

1. The upper bracket spans the entire outer epithelial region: Epidermis.
2. The lower bracket spans the thick connective tissue region beneath the epidermis: Dermis.

<answer>
The correct labels for the targets in the diagram are:

Left Column (Top to Bottom):

1. Sweat pore
2. Stratum corneum
3. Stratum spinosum
4. Stratum basale
5. Dermal papillae
6. Sensory neurons
7. Sweat gland
8. Hypodermis

Right Column Brackets (Top to Bottom):

1. Epidermis (upper bracket)
2. Dermis (lower bracket)
