Meet the Lobes

-Cerebral cortex is made up of four lobes.
I. Frontal Lobe

  • Abstract thought and emotion control
  • Contains motor cortex: Sends signals to our body., controlling muscle movement.
  • Contains Broca's Area: Responsible for controlling muscles that produce speech.
  • Damage to the Broca's Area is called Broca's Aphasia: Unable to make movements to talk.
  • Motor Cortex: Left hemisphere controls the right side of the body. 
II. Parietal Lobe
  • Contains sensory cortex receives incoming touch sensations from the body.
  • Most of the parietal lobes are made up of association areas.
  • Association areas: any area associated with receiving sensory information or coordinating muscle movement.
III. Occipital Lobe 
  • Deals with vision
  • Contains Visual Cortex: interprets messages from our eyes into images we can understand.
IV. Temporal Lobe
  • Process sound sensed by our ears
  • not lateralized
  • contains Wernicke's Area: Interprets written and spoken speech. 
  • Wernike's Aphasia: Unable to understand language.

Endocrine System: A system of glands that secrete hormones.
  • Similar to the nervous system, except hormones work a lot slower than neurotransmitter.
Thyroid gland: Affects metabolism among other things. 
Pituitary Gland: Secretes many different hormones, some of which affect other glands.
Adrenal Gland: Inner part, called the medulla. Help trigger the "flight or fight" response.
Pancreas: Regulates the level of sugar in the blood.
Ovary: Secretes female sex hormones
Testis: Secretes male sex hormones
