Laboratory animal studies show that sildenafil citrate expiration date the reticulospinal tracts control relatively automatic movements, such as maintaining posture or walking over even terrain. The various descending pathways in the spinal cord are illustrated on the right side of Figure 9-6. The tectospinal tract (Figure 10-6B ) originates primarily from neurons located in the deeper layers of the superior colliculus, which is also termed the tecturn , the portion of the midbrain dorsal to the cerebral aqueduct (see Figure 9-7A ).
It therefore participates primarily in the control of neck, shoulder, and upper trunk muscles. The reticulospinal tracts descend predominantly in the ipsilateral spinal cord but exert bilateral motor control effects. It is likely that the tectospinal tract is important for coordinating head movements with eye movements, because the superior colliculus also plays a key role in controlling eye movements.
The tectospinal tract also has a limited rostrocaudal distribution, projecting only to the cervical spinal segments. The ascending somatic sensory pathways (see Chapter 7 ) are illustrated on the left side.

Fever, depression, weight loss and pulmonary oedema with dyspnoea accompany sildenafil citrate expiration date this stage of parasite division. The merozoites produced at these divisions can enter erythrocytes as well as further lymphocytes and here give rise to the characteristic small piroplasm forms. Further schizogony occurs in red cells.
Parva preferentially invades T lymphocytes and sildenafil citrate expiration date T. Annulata prefers B lymphocytes. In some way not yet understood, the parasite then orchestrates lymphocyte proliferation so that there is a clonal expansion of infected cells with parasites and leukocytes dividing synchronously (reviewed in Dyer and Tait, 1987).
