Anat-The Brain

four major parts of the brain brainstem, cerebellum, diencephalon, cerebrum
function/location of brainstem connects spinal cord to the brain
parts of the brainstem medulla oblongata, pons, mesencephalon
location of medulla oblongata connects to the spinal cord (continuation of it??)
location of pons swelling on the anterior side of the brainstem
location of mesencephalon deep, connects brainstem and human brain (the rest of the brain)
nucleus concentration/collection of neuron cell bodies in the CNS that carries out a particular function
function of medulla oblongata regulates heart rate, blood vessel diameter, respiration, and swallowing and reflexive actions: vomiting, hiccupping, coughing, and sneezing
function of pons "bridge", connects brain's parts so that action potentials can flow
nucleus of pons sleep and respiratory center-- can influence the respiratory nucleus in the medulla
mesencephalon midbrain
mesencephalon function #1 integral part of auditory pathway in the CNS (runs from inner ear to cerebrum)
mesencephalon function #2 produces a dopamine hormone that stimulates muscles to stop them from contracting, damage to this area can cause Parkinson's
cerebellum structure/appearance cauliflower-shaped, contains 50% of the neurons of the brain even though it's a small structure
cerebellum function involved in control of balance, posture (receives positional information to maintain balance and posture), locomotion, and fine motor coordination producing smooth, flowing movements
cerebellum function example playing the piano properly VS. banging on the keys with your fist-- adds details to signals from the brain (play the piano) and coordinates awareness of position and necessary adjustments
components of diencephalon thalamus (walls), epithalamus (posterior wall), and hypothalamus (floor)
diencephalon structure surrounds a cavity, tissue is the walls, floor, etc.
thalamus structure largest part of the diencephalon
thalamus function #1 most sensory information projects here before going to the cerebrum (except for olfaction-- goes directly to the cerebrum)
thalamus function #2 filters the sensory information (ex. filters out background noise when having a conversation in a noisy room)
thalamus function #3 influences mood and actions such as fear, anger, or rage
major structure epithalamus pineal gland (endocrine)
pineal gland function may influence the sleep-wake cycle (Circadian rhythm) by producing melatonin which induces sleepiness
hypothalamus function #1 ANS control
hypothalamus function #2 endocrine control (pituitary gland is an anterior extension of the hypothalamus); regulates growth, maturity of sexual organs, metabolic rate, and reproduction
hypothalamus function #3 muscle control (Ex. shivering, swallowing)
hypothalamus function #4 temperature regulation (shivering and sweating)
hypothalamus function #5 regulation of food and water intake, "hungry" and "thirsty" signals go here
hypothalamus function #6 emotions: anger, aggression, fear, pleasure, contentment, sex drive, orgasm
hypothalamus function #7 regulation of sleep-wake cycle, controls the production of melatonin by the pineal gland
cerebrum hemispheres (halves) right and left
cerebrum lobes frontal, parietal, occipital, temporal (all under corresponding bones), and insula (deep, can't see it externally)
cerebrum function center for cognition, intelligence, individuality, memory, foresight, emotions, muscular control, interpretation of sensory data, and understanding of the world
gyrus fold
sulcus groove
meninges connective tissue membranes that surround the brain and are continuous with those of the spinal cord
superficial meninx dura mater
middle meninx arachnoid mater
deep meninx pia mater
dura mater structure has sinuses for blood to circulate
pia mater location bound tightly to the brain
subdural space function contains serous fluid
subarachnoid space function contains cerebrospinal fluid (CSF)
epidural space function NOTHING!! dura mater basically contacts the skull bones
ventricles cavity spaces in the brain that connect with each other and the central canal of the spinal cord (ventricles are derived from here)
central canal tiny hole in the center of the spinal cord
ventricle names lateral ventricles (2), third ventricle, fourth ventricle
fourth ventricle location between cerebellum and pons (in brainstem)
lateral ventricles location/structure one in each hemisphere, c-shaped/horseshoe shaped
third ventricle location/structure really thin space in the diencephalon, connected to each of the lateral ventricles
choroid plexuses location extensions in the walls of ventricles
choroid plexuses function filter and alter fluid from blood to make CSF, which fills the ventricles and other parts of the brain and spinal cord in the subarachnoid space
CSF characteristics similar to serum (formed from blood fluid) with most of the proteins removed
CSF function #1 bathes the brain and spinal cord
CSF function #2 provides a protective cushion around the CNS, absorbs some impact energy
CSF function #3 provides some nutrients (such as glucose) to CNS tissues
production of CSF produced by ependymal cells in the ventricles of the brain
the brain receives _________________ of blood pumped by the heart 15-20%
arteries through which brain receives blood right and left internal carotid arteries (through the carotid canal) and right and left vertebral arteries (through the foramen magnum)
results of several minutes of interruption to blood flow to the brain unconsciousness and irreversible brain damage
corpus callosum connects the left and right hemispheres of the cerebrum
