What is the function of the antennae?

Antennae: Segmented appendages attached to the head above the mouthparts, with important sensory functions, including touch, smell, and in some cases hearing.

What is the purpose of antennae?

The primary function of antennae is the assessment of the chemical and physical characteristics of the environment. Detection is made with innervated chemosensory and mechanosensory organs that are arrayed on the antennae. A single antenna usually has sensory organs of several types, with different properties.

What are antennae made of?

Antennae ( sg. antenna), sometimes referred to as feelers, are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.

What is ventral and dorsal?

What is the difference between dorsal and ventral? The main difference between dorsal and ventral is the area of the body to which they refer. In general, ventral refers to the front of the body, and dorsal refers to the back. These terms are also known as anterior and posterior, respectively.

What are spindles?

Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.

How do spindles work?

A spindle provides the twist that turns fiber into yarn. When using a hand spindle, your hands let the fibers slide past each other and then let the twist catch them, a process known as drafting. The size of the yarn is determined by how much fiber is caught in the twist.
