Human Brain by Mind Map: Human Brain

1. premotor cortex

1.1. responsible for dinating learned movements

1.2. controls the Speech center broca's area

2. 5 senses

2.1. sight = ability to see

2.2. sound = ability to hear

2.3. touch = ability to physically feel

2.4. smell = ability to distinguish scent

2.5. taste = ability to taste

3. frontal lobe

3.1. part of the brain that controls important cognitive skills

3.2. emotional expression, problem solving, memory, language, judgment, and sexual behaviors

3.3. control panel for our personality and our ways of communication

4. fornix

4.1. c shaped bundle of fibers that act as the major output tract of the hippocampus.

4.1.1. part of the limbic system

5. precentral gyrus

5.1. surface of the posterior lobe

5.1.1. primary motor complex (brodmann area 4)

6. central sulcus

6.1. fold in the cerebral cortex

6.1.1. central fissure

6.1.1.1. separates the frontal lobe and the parietal lobe and the primary motor complex from the primary somatosensory cortex

7. postcentral gyrus

7.1. located in lateral parietal lobe

7.2. primary somatosensory cortex

7.3. main sensory area for the sense of touch

7.4. map of sensory space in this location called the sensory homunculus

8. diencephalon

8.1. thalamus

8.1.1. largest portion of the brain

8.1.2. contains relay and the processing center for sensory information

8.2. hypothalamus

8.2.1. narrow stalk connects to pituitary gland

8.2.1.1. pituitary gland

8.2.1.1.1. the primary link between nervous and endocrine system

8.2.2. contains centers that involve emotion autonomic functions and hormone production.

8.3. pineal gland (part of the epithalamus)

9. parieto-occipital sulcus

9.1. grove in the cerebral cortex separating the precuneus of the parietal lobe from the cuneus of the occipital lobe on the medial surface of cerebral cortex

9.2. main center for visual processing

10. cerebellum

10.1. receives info from the sensory systems the spinal cord and the other parts of the brain and regulates the motor movement

10.1.1. coordinates voluntary movement

10.1.1.1. controls speech ,posture, balance, smooth balance of muscle activity

11. brain stem

11.1. stem controls the flow of messages between the brainand the rest of the body, also controls basic body functions

11.1.1. pons

11.1.1.1. relay signals from the forebrain to the cerebellum

11.1.1.2. deal primarily with sleep, respiration, Swallowing , bladder control, hearing,equilibrium, taste, eye movement, facial expressions, facial sensation, and even posture

11.1.2. medulla oblongata

11.1.2.1. portion of the hind brain

11.1.2.2. controls the autonomic functions

11.1.2.3. breathing, digestion, heart and blood vessel function,swallowing and sneezing

11.1.2.4. motor and sensory neurons from the midbrain and forebrain travel through the medulla

11.1.2.5. vagus nerve exits from here

11.1.3. midbrain

11.1.3.1. mesencephalon

11.1.3.1.1. region of the developing vertebrate brain composed of the tectum tegmentum

11.1.3.1.2. serves important functions in motor movement

11.1.3.1.3. movements of the eye and the auditory visual processing

12. temporal lobe

14.4. a turning point in evolution

15. parietal lobe

15.1. back of the brain

15.2. divided into two hemispheres

15.3. processing the sensory information regarding the location of pars of the body

15.4. interpreting visual information and processing language and mathematics

16. occipital lobe

16.1. one of the four main lobes

16.2. region of cerebral cortex

16.3. vital for receiving processing and interpreting sensory information.

16.4. positioned at the posterior region of cerebral cortex

16.5. main center for visual processing

17. lateral sulcus

17.1. sylvian fissure or lateral fissure
