About This Presentation

Description : Check out this medical PowerPoint presentation titled "Brain Anatomy” by David A. Sun, M.D., PhD.

This medical PowerPoint presentation is about the brain, the most complex organ in the human body, responsible for controlling all of our thoughts, behaviors, and bodily functions. It is a soft, spongy mass of tissue that is protected by the skull and surrounded by protective membranes called meninges.

The brain is divided into three main parts: the cerebrum, the cerebellum, and the brainstem.

The cerebrum is the largest part of the brain and is responsible for consciousness, voluntary movements, sensation, and perception. It is divided into two hemispheres, the left and right hemispheres, which are connected by a bundle of nerve fibers called the corpus callosum. The cerebrum is further divided into four lobes: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe, each of which is responsible for specific functions.

The cerebellum is located at the back of the brain and is responsible for coordinating movement and maintaining balance and posture.

The brainstem is located at the base of the brain and is responsible for controlling many of our involuntary functions, such as breathing, heart rate, and blood pressure. It is also involved in controlling the sleep-wake cycle and regulating arousal and attention.

The brain is composed of specialized cells called neurons, which transmit information throughout the brain and body using electrical and chemical signals. These neurons are supported by a variety of other cells, including glial cells, which provide structural support, nourishment, and insulation for the neurons.

Overall, the anatomy of the brain is incredibly complex, with many different structures and systems working together to support our thoughts, behaviors, and bodily functions.

Transcript

Slide 1-

Brain Anatomy Regions and their functions
Slide 2-

4 major regions Cerebral hemispheres Diencephalon Brain stem Cerebellum
Slide 3-

Cerebral Hemispheres Right and Left  Superior part of brain Most of mass of the brain Shallow groove = sulcus Elevated area by grooove = gyrus
Slide 4-

Cerebral Cortex .125 inch thick… 40% of brain mass Motor areas Sensory areas Association areas Contralateral control
Slide 5-

Central sulcus Precentral gyrus = primary motor
Slide 6-

Primary Motor Cortex Precentral gyrus
Slide 7-

Premotor Cortex Learned motor skills
Slide 8-

Broca’s area
Slide 9-

Sensory Areas
Slide 10-

Primary Somatosensory Cortex Postcentral gyrus
Slide 11-

Somatosensory Association cortex Posterior to postcentral gyrus
Slide 12-

Visual area Extreme posterior tip of occipital lobe
Slide 13-

Visual Association Area Surrounds the visual area… determines what you are seeing i.e. 2 pretty eyes, short hair, ears… its Rihanna!
Slide 14-

Auditory Areas Top of temporal lobe = primary auditory area Posterior of temporal lobe = auditory association area
Slide 15-

Olfactory cortex  primitive brain new functions Rhinencephalon = Memory! Why we remember smell of Grandma’s old smoky apartment, with dentures and those weird mints now only seen at midlevel restaraunts
Slide 16-

Diencephalon 3 paired structures Thalamus Hypothalamus Epithalamus
Slide 17-

Thalamus Large number of nuclei “Afferent impulses from all senses and all parts of the body converge on the thalamus Includes sensory, visceral, emotional, etc.
Slide 18-

Hypothalamus 7 functions 1.) Autonomic control center 2.) Center for emotional response 3.) Body Temperature Regulation
Slide 19-

Hypothalamus 4.) Regulation of Food Intake 5.) Regulation of Water balance and thirst 6.) Regulation of sleep-wake cycles 7.) control of endocrine system functioning
Slide 20-

Epithalamus Pineal gland – melatonin hormone
Slide 21-

Brain Stem
