Pore (material), one of many small openings in a solid substance of any kind that contribute to the substance's porosity (typical usage in earth sciences, materials science and construction) A small defect in the crystal structure that may arise during sintering to form solids from powders, including ceramics
The human nuclear pore complex (hNPC) is a substantial structure, with a molecular weight of 120 megadaltons (MDa). [13] Each NPC comprises eight protein subunits encircling the actual pore, forming the outer ring. Additionally, these subunits project a spoke-shaped protein over the pore channel.
Human sweat gland pores on the ridges of a finger pad. The number of active sweat glands varies greatly among different people, though comparisons between different areas (ex. axillae vs. groin) show the same directional changes (certain areas always have more active sweat glands while others always have fewer).

The human skin is the outer covering of the body and is the largest organ of the integumentary system. The skin has up to seven layers of ectodermal tissue guarding muscles, bones, ligaments and internal organs. Human skin is similar to most of the other mammals' skin, and it is very similar to pig skin.
There are three parts to the eccrine sweat gland and these are the pore, the duct, and the gland. The pore is the portion that goes through the outermost layer of the skin and is typically 5-10 microns in diameter. The duct is the part of the sweat gland that connects dermis cells to the epidermis. It is composed by two layers of cells and is ...
Micro CT of porous medium: Pores of the porous medium shown as purple color and impermeable porous matrix shown as green-yellow color. Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of pore channels) of a porous medium.

Nuclear pores crossing the nuclear envelope. The nuclear envelope is punctured by around a thousand nuclear pore complexes, about 100 nm across, with an inner channel about 40 nm wide. [9] The complexes contain a number of nucleoporins, proteins that link the inner and outer nuclear membranes. [citation needed]
