The tectospinal tract connects the midbrain and the spinal cord. It is responsible for motor impulses that arise from one side of the midbrain to muscles on the opposite side of the body. The function of the tectospinal tract is to mediate reflex postural movements of the head in response to visual and auditory stimuli. Damage signs would show prevention in being able to coordinate the head‚ neck‚ and eye movements. Sensory receptors perform countless functions in our bodies including mediating vision

sheaths around nerve fibers in the CNS. 6. Nerve fibers with many Schwann cells forming a thick myelin sheath are called myelinated fibers‚ or gray fibers. 8. Most of the neurons in the brain and spinal cord are unipolar. 9. In a contralateral reflex arc‚ the receptors and effectors are located on opposite sides of the body. 10. In an ipsilateral arc‚ the effectors and receptors are on opposite sides of the body. 11. Groups of cell bodies located in the brain or spinal cord are referred to as

Harrison‚ 1981). B. Diving. 1. Beluga whales typically don’t dive very deep‚ usually to about 20 m (66 ft.). Belugas are not generally thought of as deep-diving marine mammals‚ but they are capable of diving to extreme depths. Under experimental conditions a trained beluga whale repeatedly dove to 400 m (1‚312 ft.) with ease‚ and even dove to a depth of 647 m (2‚123 ft.) (Nowak‚ 1991; Ridgway et. al.‚ 1984). 2. A typical dive usually lasts three to five minutes‚ but belugas can stay submerged
