1 C h a p t e r 15 The Nervous System: The Brain and Cranial Nerves PowerPoint Lecture Slides prepared by Jason LaPres North Harris College Houston, Texas Copyright 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings
2 Introduction The brain is far more complex than the spinal cord. The brain contains roughly 20 billion neurons. Excitatory and inhibitory interactions among the extensively interconnected neuronal pools ensure that the response can vary to meet changing circumstances.

21 Protection and Support of the Brain Figure 15.8 Hydrocephalus This infant has severe hydrocephalus, a condition usually caused by impaired circulation and removal of cerebrospinal fluid. CSF buildup leads to distortion of the brain and enlargement of the cranium.
22 The Cerebrum The cerebrum is the largest, most superior portion of the human brain. Each cerebral hemisphere receives sensory information from and generates motor commands to the opposite side of the body. The two hemispheres have some functional differences, although anatomically they appear to be identical.

41 The Diencephalon The diencephalon connects the cerebrum to the brain stem both structurally and functionally. The functions that occur in the diencephalon are almost exclusively subconscious. Epithalamus controls the circadian rhythm Thalamus relays information Hypothalamus coordinates the nervous and endocrine systems

50 The Diencephalon
51 The Mesencephalon The mesencephalon, or midbrain, is the most superior portion of the brain stem. Nuclei coordinate visual and auditory reflexes. Corpora quadregemina Superior colliculi visual Inferior colliculi auditory Limbic system nuclei Coordinate involuntary movements of skeletal muscles Cerebral peduncles Nerve bundles to and from the brain/spinal cord

58 The Mesencephalon
59 The Pons The pons mainly functions: As a house for cranial nerve nuclei V, VI, VII, and VIII To help regulate respiration To help coordinate involuntary skeletal muscle movements and muscle tone In relaying information to and from the brain/spinal cord
60 The Pons Figure The Pons
61 The Pons
62 The Cerebellum The cerebellum has two primary functions: Adjusts the postural muscles of the body to maintain balance Programs and fine-tunes voluntary and involuntary movements
63 The Cerebellum Figure 15.19a The Cerebellum (Posterior, Superior Surface)
64 The Cerebellum Figure 15.19b The Cerebellum (Sagittal Section)
65 The Cerebellum
66 The Medulla Oblongata The medulla oblongata physically connects the brain with the spinal cord. It is so important that, if it is severely compromised, the victim will likely die. The medulla oblongata is a relay station, house for cranial nerve nuclei, and most importantly, controls visceral functions like blood pressure, breathing, and heart rate.
