Poets who use more traditional, metaphoric language like Italy's Valerio Magrelli, Sweden's Hakan Sandell, and Ireland's Nuala Ni Dhomhnaill are presented alongside those who use a more literal, colloquial language, like Romania's Simona Popescu or Ukrainian poet Yuri Andrukhovych (see WLT, September 2005, 24-32).
Skeletal muscle fibers are made when myoblasts fuse together; muscle fibers therefore have multiple nuclei (each nucleus originating from a single myoblast). The fusion of myoblasts is specific to skeletal muscle (e.g., biceps brachii) and not cardiac muscle or smooth muscle.ardiomyocytes are the muscle fibres that form the chambers of the heart, and have a single central nucleus. Skeletal muscle fibers help support and move the body and tend to have peripheral nuclei. Smooth muscle cells control involuntary movements such as the peristalsis contractions in the oesophagus and stomach.
In order for skeletal muscle cells (muscle fibers) to contract, it is imperative they have communication with a motor neuron. A motor neuron is a nerve cell whose cell body is located in the spinal cord or brain. The axon of the nerve cell meanders toward the muscle it supplies. As it reaches the muscle, it branches: each branch going to a muscle fiber. The motor neuron, its axon branches, and all the muscle fibers it supplies is known as a motor unit and each muscle consists of numerous motor units (See Figure 1).
