Nervous System

Medulla Oblongata Function

Medulla Oblongata Function

1. Heart Rate

2. Breathing

3. Blood Pressure

4. Reflex reaction (coughing, sneezing, vomiting)

Pons Function

1. Waking/dreaming

2. Respiration

3. Facial Muscles

Thalamus Function

1. Receives sensory information, sends impulses to other regions of the cerebrum

2. Part of RAS system

RAS

Reticular Activating System, sorts incoming stimuli

Cerebellum Function

controls balance and complex movement

hypothalamus Function

1. homeostasis(hunger, sleep, thirst, body temp, water balance, blood pressure, controls pituitary glands)

pituitary gland Function

regulates growth, metabolism, and reproduction by producing hormones

Corpus Callosum

transmits informations between cerebral hemispheres

Four main lobes

Frontal, Parietal, Temporal, Occipital

Frontal Lobe Functions

1. movement

2. speech production

3. judgement, plan making

4. personality and emotion

Parietal Lobe Function

1. processing sensory information

Temporal

1. hearing

2. organization and comprehension of language

3. memory access

Occipital

2. Vision

   1. Combining visual experiences with other sensory experiences.

Neuroendocrine System

nerves and gland cells that creates and releases hormones to the bloodstream. Include the pituitary and is controlled by the hypothalamus

Posterior Pituitary

Stores and releases hormones made by the hypothalamus. (Antidiuretic hormone=water regulation, oxytocin=trust, arousal, romantic connection)

Anterior Pituitary

hormones from the hypothalamus stimulate the release of hormones created by the anterior pituitary, connected by a portal blood vessel system. (growth hormone, melatonin)

White matter

composed of axons, communication between areas of gray matter

Gray matter

composed of somas and dendrite, where the actual “processing” of information takes place

Amygdala

processing fearful and thrustful stimuli, associated with aggression and fear

midbrain

topmost part of the brain stem, processes visual and auditory signals

reticular formation

regulator of arousal and consciousness

Autonomic Nervous System

• controls internal organs

• unconsciously controlled

Somatic Nervous System

• serves musculoskeletal system and sense organs

• consciously controlled
