C&b 013/4 Muscles And Blood Vessels

Front 1

Smooth muscle cells have elongated nuclei, are cigar shaped, not usually with a distinct nucleolus, situated towards the centre of the cell

Back 1

Fibroblast nuclei tend to be pointy, and are often curved, bent or wavy: smooth muscle cell nuclei are not, and tend to be plumper.

Front 2

Unlike striated muscle, in smooth muscle... (ref to: nuclei)

Back 2

Large areas devoid of nuclei are never found.

Front 3

How do smooth muscle cell nuclei differ from fibroblast nuclei?

Fibroblast nuclei tend to be pointy, and are often curved, bent or wavy: smooth muscle cell nuclei are not, and tend to be plumper.

Front 4

What is the only organ in which striated and smooth muscle fibres intermingle?

Back 4

The oesophagus

Front 5

Skeletal muscle is striated muscle, T/F

Back 5

T

Front 6

Skeletal (= striated) muscle cells have round/oval nuclei, with small but distinct nucleoli, the nuclei are usually at the edge of the cell. The cells are very long, a number of mm or cm, and contain many nuclei.

Back 6

In areas of striated muscle, large regions may appear to be devoid of nuclei.

The heart wall is also known as the...
