| The chloroplasts of some plants show the invagination of the inner membrane into granum particularly in Sorghum, maize and sugarcane. |
|
| A slight invagination of the ectoderm occurs, and a cloacal membrane forms, separating the ectodermal invagination from the gut cavity. |
|
| One major characteristic is the invagination of the epidermis in the equivalent of the dermis. |
|
| After establishing a tight junction with the erythrocyte membrane, the merozoite actively enters into what looks like an invagination of the red cell membrane. |
|
| As the red cell is not a phagocytic cell, it must be assumed that, prior to membrane invagination, considerable changes in the shape of the cell will have to take place. |
|
| The ovary of many teleosts, especially viviparous ones, contains a permanent cavity, which is formed during ovarian development when an invagination of the ovarian surface traps a portion of the coelom. |
|
| This helical arrangement, well known to surgeons who observe it after invagination of the long saphenous vein, appears to be related to the embryological development of the vein. |
|
| Pagetic involvement at the base of the skull may lead to basilar invagination or platybasia with consequent compression of structures in the posterior fossa, spinal cord or, rarely, cerebellar tonsillar herniation. |
|
| The formation of a spore begins with invagination of the cytoplasmic membrane around a copy of the bacterial chromosome, thus separating the contents of the smaller cell from the mother cell. |
