How many cranial nerves are responsible for eye movement and what are they - 3 they are Cranial Nerves III, IV, and VI (3,4,6) The action of acetylcholine is quickly terminated by its being hydrolyzed by the enzyme - acetylcholinesterase. Adrenergic fibers release - norepinephrine = adrenaline Afferent - Afferent neurons are sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain Cholinergic fibers release - acetylcholine (ACh) cranial ...

VCE Psychology AOS 1 Complete Solutions Central Nervous System Consists of the brain and spinal cord. The Brain Network of cells that plays vital role in processing neural information, and directing actions within the body. Has integrating and overlapping functions. Spinal Cord Links the brain and the rest of the body via the PNS, involves simple reflex responses independently of the brain. Peripheral Nervous System Entire network of nerves located outside the CNS. Carries a...

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...

Bio 253 Exam 2 Graded A+ Dorsal root has what kind of fibers Sensory Fibers (afferent) Venerate Root has what kind of fibers motor fibers (efferent) Significance of the phrenic nerve it's housed in the cervical plexus innervates the diaphragm Which plexus houses the ulnar Brachial plexus The ramus is large branches formed after each spinal nerve emerges from the spinal cavity. The dorsal ramus supplies somatic motor and sensory fibers to smaller nerves that innervate the muscles a...

N5315 Advanced Pathophysiology Neuro Anatomy and Physiology Overview - The nervous system is responsible for regulating and coordinating all body systems - CNS = brain and spinal cord - PNS = 12 pairs of cranial nerves and 31 spinal nerves • Further subdivided into Somatic Nervous System and Autonomic Nervous System • Afferent and efferent pathways → responsible for transmitting information ~ Afferent nerves = sensory nerves → carry impulses from cells, tissues, and organs to CNS...

VCE Psychology Unit 3: AOS 1 Already Graded A The central nervous system (CNS) the network of nerves and neurons that make up the brain and spinal cord. Both are encased with bone for protection. Role of the central nervous system to process information provided by the sensory systems and the other parts of the body and to activate appropriate actions. The brain (CNS) an intricate network of nerve tissues (clusters of neurons) that plays a vital role in processing information receive...
