Where can you find bipolar neurons? Retina of the eye, olfactory region, and inner ear Where can you find unipolar neurons? Most sensory Where can you find multipolar neurons? Most CNS and efferent neurons Neuroglia of the CNS -astrocytes (blood-brain barrier) -microglial cells -ependymal cells -oligodendrocyte Neuroglia of the PNS -Schwann cells -satellite cells Olfactory nerve (CNI) 1- Smell Optic nerve (CNII) 2- visual

Ras signaling - GTPase - promotes growth and proliferation - mutated in 20-30% of all cancers - point mutations are most common G12V mutation - blocks GAP binding - locks RAS in active state, promoting proliferation Q61K mutation - raises activation energy of GTP hydrolysis - blocking hydrolysis, keeping RAS active Hallmarks of cancer 1) self-sufficiency in growth signals 2) insensitivity to anti-growth signals 3) unstable DNA 4) metastasis 5) evasion of apoptos...

CHAPTER 3 NEUROSCIENCE CHAPTER LEARNING OBJECTIVES 1. Understand the key methods that scientists use to learn about brain anatomy and functioning. • Neuroscientists examine autopsy tissue and patients with localized brain damage to learn about brain anatomy and brain function. • EEGs and neuroimaging, such as PET scans and fMRI, allow scientists to study brain function in the living brain. 2. Describe the two major types of cells in the nervous system and describe the prima...

Portage Learning BIOD 152 A&P 2 Final Exam 2023/2024 Identify the parts of the neuron shown in the diagram below a. dendrite b. cell body c. nucleus List the four parts of the human brain The human brain is made up of the cerebral hemispheres, diencephalon, brain stem, andcerebellum. List and describe the 3 meninges of the human brain. The leathery dura mater is the double-layered outer meninx. The middle arachnoid meninx is a loose layer separated from the dura...
