About this Exam
Prepare with the BCT Lab Practical 1 Practice Test practice quiz. This question bank includes 10 questions covering tissue, cells, cell, white, and canal. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
Schwann cells make ______ in the CNS.
Explanation:
In the central nervous system, myelination is done by oligodendrocytes, not Schwann cells. Schwann cells are the glial cells that form the myelin sheath around peripheral nerves. CSF is produced by the choroid plexus ependymal cells, and mucus is produced by mucous membranes, not by Schwann cells. Therefore, Schwann cells do not make any of the listed substances in the CNS, so none of the options apply.
Question
2
The naming of epithelial tissue is based on the shape of the cells on the basal surface.
Explanation:
Epithelial tissue is named by how many cell layers there are and by the shape of the cells at the surface that faces the lumen or outside, not by the shape of cells on the basal side. The basal surface sits on the basement membrane and mainly serves for attachment and polarity; it doesn’t determine the name. The visible, apical surface shows cells that are flat (squamous), cube-shaped (cuboidal), or tall and columnar, and this apical shape is what drives the classification alongside the layering. For example, a single layer of flat apical cells is simple squamous, while multiple layers with flat outermost cells are stratified squamous. Transitional epithelium is a special case that can change shape with stretch, but the naming still relates to the surface cell appearance and layering. So naming based on the basal surface is not correct.
Question
3
Which organelle is primarily responsible for steroid production in the cell?
Explanation:
Steroid hormones are lipid-based molecules built from cholesterol, so their production relies on the lipid-synthesis machinery of the cell. The smooth endoplasmic reticulum provides the membrane-rich environment and the enzymes needed to carry out the steps that convert cholesterol into the various steroid hormones. While the initial cholesterol modification to pregnenolone starts in the mitochondria, most of the subsequent steps that finalize different steroids occur in the smooth ER. That combination makes the smooth ER the primary site for steroid production.
Question
4
Which tissue type in the cerebellum is white matter?
Explanation:
In the cerebellum, white matter is the inner core composed of myelinated axons, forming the arbor vitae that connects the cerebellar cortex with other brain regions. The cortex of the cerebellum is gray matter, organized into three layers: molecular, Purkinje cell, and granular layers, all containing neuron cell bodies and unmyelinated fibers. Because of the myelin, the white matter appears lighter. So the tissue type that is white matter is the central, myelinated fiber tracts of the cerebellum, while the three gray layers lie on the surface.
Question
5
Which statement is true about white and red blood cells?
Explanation:
White blood cells keep their nucleus to support ongoing gene expression and immune functions, while mature red blood cells lose their nucleus (and, in mammals, mitochondria) to maximize space for hemoglobin and to be more flexible through tiny vessels. That combination makes the statement true: white blood cells are nucleated and red blood cells are anucleated. The other ideas conflict with what mature blood cells look like—red blood cells do not have nuclei (and typically lack mitochondria in mammals), white blood cells do have nuclei, and not all blood cells share the same nuclear status.
