HEAD AND CERVICAL SPINE

Brain Anatomy

 

Brain

• Cerebrum: Responsible for motor function, sensory information, special senses, cognition, and memory

  • Frontal lobes: responsible for problem solving and judgment and motor function.

  • Parietal lobes: manage sensation, handwriting, and body position.

  • Temporal lobes: involved with memory and hearing.

  • Occipital lobes: brain's visual processing system.

• Cerebellum: Responbile for balance, coordination, and smooth, synergistic muscle control

• Diencephalon: Routing afferent info to appropriate cerebral areas, regulation of body temperature, maintaining homeostasis and emotional control.

• Brain Stem: Regulates heart and respiration rate and controls flow of peripheral blood. 

 

Meninges

• Membranes that surround and protect the brain.

• Dura Mater: Strongest, outermost layer; name literally means "tough mother". 

• Subdural space: Separates dura mater and arachnoid mater

• Arachnoid Mater: Resembles a spiderweb; middle and most fragile layer.

• Subarachnoid Space: beneath the arachoid mater, holds cerebral spinal fluid. 

• Pia Mater: Innermost layer that forms the brain's outer skin.
