This is endosteum.
Endosteum.
It is called cristae. There are inner foldings
Spongy inner layer called cancellous bone. Spongy bone is lighter and less dense than compact bone
I think you are referring to the cristae. These are the folded parts of the inner membrane. The purpose is to increase surface area of the inner membrane against the matrix. The membrane is the site of the energy transfer in the mitochondria, so having more surface area is a plus.
Trabecular bone.
bone marrow
The layer beneath the outer membrane is called the periplasmic space or the periplasm. It is a gel-like region that contains proteins and other molecules, and it separates the outer membrane from the inner membrane in Gram-negative bacteria.
it is periosteum
The outer membrane is smooth, while the inner membrane is convoluted into folds called cristae in order to increase the surface area
The periosteum is the membrane around the shaft of a long bone.
It is called cristae. That is due inner foldings
The inner folds of the mitochondria membrane are called cristae. These structures increase the surface area of the inner membrane, allowing for more space for the electron transport chain and ATP synthesis to occur.
The convolutions in the inner membrane of a mitochondrion are referred to as the cristae. Mitochondrion refers to an organelle found in most cells whereby energy production and respiration takes place.
