Occasionally we did so badly we stopped midpiece and my daughter would start to laugh.

He stopped abruptly, in midpiece, as if a light had fused; pretension began again.

The cell is comprised of an acrosome, head region, midpiece and single flagellum.

The cell possesses a distinct acrosome, a midpiece, and a single flagellum.

An elongated anaphase interzonal midpiece is formed which breaks down at telophase.

The spermatozoon of Chondrichthyes is characterized by two synapomorphies in the midpiece and the flagellum.

A discrete midpiece is lacking.

The anterior part of the tail (called midpiece) thickens because mitochondria are arranged around the axoneme to ensure energy supply.

The midpiece is very long (a synapomorphy of the Serpentes) and is surrounded by a multilaminar membrane (an autapomorphy).

Indirect immunofluorescence of non-capacitated spermatozoa with the angiotensin II type 1 receptor antibody revealed labelling in the midpiece and tail.

The structures of the midpiece are shown, including a unique mitochondrial "skirt" that includes densely packed parallel cristae and extends in a narrow sheet from the mitochondria.

The midpiece has a central filamentous core with many mitochondria spiralled around it, used for ATP production for the journey through the female cervix, uterus and uterine tubes.

Entry of these cells into the epididymis is accompanied by sudden activation of the tyrosine phosphorylation pathway, initially in the principal piece of the cell and subsequently in the midpiece.

He made a midpiece modulation from G to F in "I Lombardi" specifically to give the soprano high A's instead of B's, "because that note is particularly effective" in the particular singer's voice.

In addition, we were able to confirm that the structural arrangement of the distal centriole of the midpiece is identical with that of the proximal centriole: nine sets of microtubular triplets around the periphery of the centriole.

Mature spermatozoa are filiform and are characterized by features such as a depression in the transverse section of the acrosome, a moderately long midpiece, columnar mitochondria, an elongated nucleus, and a fibrous sheath in the midpiece.
