Slide3 l.jpg

If Christopher is in a car accident and due to brain damage loses his sight, which lobe of the brain were probably damaged?

Occipital

When you go to the refrigerator and reach for a carton of milk, which lobes of the brain are you using?

Frontal & Occipital

When you are listening to music on earphones, which lobe of the brain are you using?

Temporal

When an Olympic gymnast does a flip on the balance beam, which lobes of the brain is she using?

Frontal, Occipital,

Parietal, & Temporal


Regions of the brain l.jpg
Regions of the Brain loses his sight, which lobe of the brain were probably damaged?

  • Brain stem

  • Cerebellum

  • Cerebral hemispheres

  • Diencephalon

Surface is made of ridges (gyri) and grooves (sulci) purpose: to increase surface area

Figure 7.12b


Specialized areas of the cerebrum l.jpg
Specialized Areas of the Cerebrum loses his sight, which lobe of the brain were probably damaged?

Somatic sensory area – receives impulses from the body’s sensory receptors (audio, visual, olfactory, and taste)

  • Interpretation areas of the cerebrum

    • Speech/language region

Broca’s area – involved in our ability to speak

Figure 7.13c


Motor areas of the cerebral cortex l.jpg
Motor Areas of the Cerebral Cortex loses his sight, which lobe of the brain were probably damaged?

Primary motor area – sends impulses to skeletal muscles

Figure 7.14


Layers of the cerebrum l.jpg
Layers of the loses his sight, which lobe of the brain were probably damaged?Cerebrum

  • Gray matter

    • Outer layer

    • Composed mostly of neuron cell bodies

      White matter

    • Fiber tracts inside the gray matter

    • Example: corpus callosum connects hemispheres

Figure 7.13a


Diencephalon l.jpg
Diencephalon loses his sight, which lobe of the brain were probably damaged?

  • Sits on top of the brain stem

  • Enclosed by the cerebral hemispheres

  • Thalamus

  • Hypothalamus

  • Epithalamus


Thalamus l.jpg
Thalamus loses his sight, which lobe of the brain were probably damaged?

  • Surrounds the third ventricle

  • The relay station for sensory impulses

  • Transfers impulses to the correct part of the cortex for localization and interpretation


Hypothalamus l.jpg
Hypothalamus loses his sight, which lobe of the brain were probably damaged?

  • Under the thalamus

  • Important autonomic nervous system center

    • Helps regulate body temperature

    • Controls water balance

    • Regulates metabolism

  • An important part of the limbic system (emotions)

  • The pituitary gland is attached to the hypothalamus


Epithalamus l.jpg
Epithalamus loses his sight, which lobe of the brain were probably damaged?

  • Forms the roof of the third ventricle

  • Houses the pineal body (an endocrine gland)

  • Includes the choroid plexus – forms cerebrospinal fluid


Brain stem l.jpg
Brain Stem loses his sight, which lobe of the brain were probably damaged?

  • Attaches to the spinal cord

  • Parts of the brain stem

    • Midbrain

    • Pons

    • Medulla oblongata


Midbrain l.jpg
Midbrain loses his sight, which lobe of the brain were probably damaged?

  • Mostly composed of tracts of nerve fibers

  • Has two bulging fiber tracts – cerebral peduncles

  • Has four rounded protrusions – corpora quadrigemina

    • Reflex centers for vision and hearing


Slide16 l.jpg
Pons loses his sight, which lobe of the brain were probably damaged?

  • The bulging center part of the brain stem

  • Mostly composed of fiber tracts

  • Includes nuclei involved in the control of breathing


Medulla oblongata l.jpg
Medulla Oblongata loses his sight, which lobe of the brain were probably damaged?

  • The lowest part of the brain stem

  • Merges into the spinal cord

  • Contains important control centers

    • Heart rate control

    • Blood pressure regulation

    • Breathing

    • Swallowing

    • Vomiting
