Increase HR, Increase Respiration, Fight and flight
Function of parasympathetic system
Decrease HR, slow respiration, rest and digest
Autonomic Nervous system
Part of PNS and Composed of Sympathetic and parasympathetic and it is not under conscious control. Such as Breathing and body temperature.
Somatic Nervous system
Part of PNS and involves movement under conscious control
Also known as Forebrain ( Telencephalon and Diencephalon) Top part of the brain
Composed of midbrain pons and medulla oblongata. It contains lots of nuclei that control respiration, body temperature. Serves also as tract for large fibers to pass through it.
Also known as the little brain and contains the cerebral cortex and nuclei. Important functions such as playing piano and fine motor movements.
Part of the CNS and is composed of dorsal, lateral, and ventral columns
Top and front portion of the brain that is involved in long term memory, planning and strategizing.
Somatosensory processing from the entire body and involved with motor control to some extent
Part of the frontal lobe involved in speech and long term planning
Part of the parietal lobe which is involved in understanding spoken word.
Grooves in the brain
Separates frontal lobe from the parietal lobe
Demarcates or defines temporal lobe
Peaks and hill, and increase the SA of the brain Gyri (1/3 SA), Sulci 2/3 of SA
Visual processing contains the visual cortex
Involved in memory processing, emotional behaviors, and auditory processing.
Splits brain into left and right hemisphere
Importaitn for motor control
Receives sensory information from body for processing.
Dominnat in mathematics, logic and language
Dominant in mapping special abilities, music face, recognition.
Cell bodies of the neurons mainly found on the outer layer of the brain
Mylenated nerve fibers (makes up the greatest part of the brain)
It means through the brain and it contains the Thalamus and hypothalamus
Relay/sorting station for sensory information.
Lateral Geniculate nucleus
Part of the thalamus involved in processing information from the from the eyes to the visual cortex fo the occipital lobe.
Part of the thalamus Receives information from the ears and relays over to the temporal lobe
Lies beneath thalamus and it is important in basic subconscious functions for instance when you get hungry it will drive you to go find food. Also controls the autonomic nervous system (regulating body temperature, circadian rhythm, expression of emotions.
Semantic memory (memory of meanings, and understanding concept based knowledge)
Important in learning memory.
Emotion and congestive memory, traumatic memory formation.
Composed of lentiform nucleus, caudate nucleus, and putamen and its involved in planning and organizing voluntary movement.
Composed of Lentiform nucleus and caudate nucleus and its important in organizing voluntary movement.
Composed of Corpus Striatum, substantia nigra, and subthalmic nuclei (controls planning of voluntary movement).
Connects the right and left hemisphere of the brain and allows them to communicate with one another.
Known as the master gland that is controlled by the hypothalamus
Composed of pineal body and habenular
Controls diurnal cycle (sleep cycle) and onset of puberty
Emotional responses to smell.
Inter thalamic adesion
Lies in between thalamus and hypothalamus. It allows the right half of the thalamus to talk to the left half of the thalamus.
What are the components of Diencephalon?
Thalmus, Epithalamus( Pineal body, harbenuar), inter thalamic adesion, pituitary gland
Nuclei of the thalamus that is involved in somatosensory, located on the belly side back of thalamus. It receives information from body and sends it to cerebrum
Located in hypothalamus The preoptic area is responsible for thermoregulation and receives nervous stimulation from thermoreceptors in the skin, mucous membranes, and hypothalamus itself.
Located in hypothalamus Regulation of body temperature, and constriction and dilation of blood vessels
Located in hypothalamus Involved in water balance and contains osmo receptors
Located in hypothalamus Regulates sleep and wake cycles
Located in hypothalamus is the part of the brain where the optic nerves (CN II) partially cross
Located in hypothalamus playing essential roles in controlling stress, metabolism, growth, reproduction, immune and other more traditional autonomic functions (gastrointestinal, renal and cardiovascular).
Lateral Area (hypothalamus)
Located in hypothalamus, and its the Feeding Center
Located in hypothalamus, and t is involved in feeding, drinking, body-weight regulation and circadian activity
Located in hypothalamus Shivering
Located in hypothalamus and involved in emotional response to smell.
Located in hypothalamus and inhibits feeding.
Part of mid brain involved in visual reflexes
Part of midbrain involved in auditory reflexes
Within pons are sleep and respitory centers, ascending and escending fiver track between cerebrum and cerebellum and cranial nuclei (V-IX)
Part of midbrain involved in sound modulation from inner ear
Ascending and descending tracts
Crossing of motor fiber involved in voluntary movement.
Part of midbrain involved in respiration, heart rate, BP, vomiting, coughing, sneezing and cranial nuclei (IX-XII)
Nerve fibers that are going up carrying sensory information through the midbrain
Part of the midbrain that consist of four colliculi (the collective term for them is Corpora quadrigemina)
Part of the midbrain that contains the red nucleus and substanita nigra
Part of the midbrain that is responsible for production of Dopamine as a the neurotransmitter
