The dermatologist examined the biopsy and noted a single basal cell at the edge of the epidermis.

Cells in the basal layer constantly divide to replace the outer epidermal cells.

During the neurological exam, the doctor noted abnormal activity in the basal ganglion that likely explained the tremor.

Functional imaging revealed increased activity in the basal ganglia during the motor task.

Under the microscope, the researcher observed how the basal body anchors the cilium to the cell surface during development.

After reviewing the patient's history, the dermatologist suspected nevoid basal cell carcinoma syndrome and ordered genetic testing.

The genetics team confirmed that his nevoid basal-cell carcinoma syndrome was responsible for the jaw cysts and multiple skin lesions noted since childhood.

The botanist carefully measured the basal tubercles on the seedpods to distinguish between species.
