medulla) a. Cerebellum - regulates reflexes & balance‚ coordinates movement [Damage cause ataxia] b. Pons - motor control & sensory analysis c. medulla - controlling heartbeat & breathing [chewing‚ swallowing‚ sneezing‚ coughing‚ salivation] Reticular Formation - lattice-like network of nerve cells w/in medulla which controls person’s state of arousal‚ sleep- waking cycle Spinal cord - stem-like running down vertebral column‚ composed nerves that lead to and from the brain

Q.2- Discuss what neuromodulators are and how they modulate the sensation of pain. The sensation and clarification of pain includes activation of individuals brain regions associated with spatial discriminative and affecting mechanisms of pain awareness. This is clearly a potential concern of movement of the primary afferent nociceptor‚ and comprises integration of the polysynaptic yield from the primary afferent through several arising pathways. The exact position of specific supraspinal regions

Task 1- tissues Tissues are groups of similar cells which have a similar structure and function. All of these cells work together to complete various tasks. There are four different types of tissues in the human body that I am going to give examples of. These include the epithelial tissue‚ connective tissue‚ collagenous tissue and the nerve tissue. The first time of tissue is the epithelium tissue which has the function of helping to protect the body. There are four main types of epithelium tissues;

movement‚ the maintenance of muscle tone‚ and various cardiac‚ circulatory‚ and respiratory reflexes. Damage to this part of the brain is life-threatening. The metencephalon also houses many tracts that both ascend and descend as part of a reticular formation. These structures create a bulge called the pons. The pons is one major division of the metencephalon. The other is the cerebellum. This is the large convoluted structure on the brain stem. Damage to this part of the brain makes it impossible

Myeloid tissue Is the bone marrow Why we discuss myeloid tissue/bone marrow? – because we want to study the development of blood cells. We called it HEMOPOEISIS/HEMATOPEISIS HEMOPEISIS/HEMATOPOEISIS –Blood cell formation (occurs in the bone group) Why study this? Because: there is a continuous replacement of cells they have short life span when they are in the peripheral circulation so‚ we have to study how these cells mature and differentiate Phases of hematopoeisis MESOBLASTIC PHASE

Spinal Cord Motor Activity Classification of Reflexes " 1- Somatic reflexes : that you are aware of them 2- Autonomic Reflexes : that control visceral organs. Examples of spinal reflexes‚ involving spinal nerves and the spinal cord‚ include: 1- extensor reflex: leg proprioceptors trigger limb extension 2- myotatic (stretch) reflex: muscle stretch is resisted by reflex contraction of the muscle 3- withdrawal (flexion) reflex: limb flexes to withdraw from a noxious stimulus

Basal ganglia Controls cognition and movement coordination as well as voluntary movement. It is also a component of the corpus striatum and it consists of the subthalamic nucleus and the substantial nigra (About.com‚ 2012). 2. Corpus collosum There is a thick band of nerve fibers and these are called
