Longitudinal Fissure

is the deep groove that separates the right and left hemispheres of the brain.

Transverse Fissure

is the deep groove that separates the cerebrum from the cerebellum.

Gyri

are the raised ridges or folds on the surface of the brain.

Sulci

(space in between)

are the shallow grooves or indentations between the gyri of the brain.

The frontal lobes are responsible for

motor activities, conscious thought, and speech, personality, planning, and impulsiveness

Posterior to the frontal lobe

The parietal lobe are responsible for

body sense, perception, and understanding language

Occipital lobe

responsible for vision

temporal lobes

involved in hearing and the integration of sensory information and memory

The insula

known as the 5th lobe, help coordinate autonomic(visceral) functions, emotion processing, taste perception, interoception(awareness of internal body sensations), Pain perception, Anxiety & addiction pathways, It connects emotional experience with physical sensations.

precentral gyrus

is the primary motor cortex of the brain.

It controls voluntary skeletal muscle movement, Sends signals to skeletal muscles, Contains the motor homunculus

postcentral gyrus

is the primary somatosensory cortex of the brain.

It is responsible for processing sensory information from the body

Brocas area located in the frontal lobe

controls motor output for speech

Wernickes area located in the parietal and temporal lobes

controls sensory aspects of language, including understanding

Cerebellum

posterior to the brain stem and plays an important role in sensory and motor coordination, balance, and cognitive functions

The brain stem last part

Medulla oblongata

responsible for impulses that control heartbeat, breathing, and the muscle tone in blood vessels, which controls blood pressure

The brain stem

Superior to the medulla oblongata

The pons

connects the medulla oblongata and the cerebellum with the upper portions of the brain, they also play a role in breathing

The brain stem

Top of the brain stem

midbrain

acts as a two way conduction pathway to relay visual and auditory impulses and other information to the cerebrum

The brain stem

receives sensory information and contains control systems for vital functions such as blood pressure, heart rate, and breathing, this controls the vital functions of life

The four fluid filled cavities in the brain are called

ventricles, they allow for the culation of cerebrospinal fluid throughout the brain

The corpus callosum

thick band of white matter fibers that connects the right and left cerebral hemispheres, It allows the two sides of the brain to communicate and share information.

The thalamus

replays and processes information going to the cerebrum

Hypothalamus

regulates hormone levels, temperature, water balance, thirst, appetite, sleep wake cycles and some emotions( pleasure and fear); regulates the pituitary gland and controls the endocrine system

Pineal Body

responsible for secretion of melatonin(body clock)

Pituitary gland

secretes hormones for various functions

The basal nuclei are

clusters of gray matter located deep within the cerebral hemispheres.

Somatic sensory system

provides sensory input for your nervous system to

Somatic sensation

allows you to feel the world around you

crude touch, vibration, pain, temperature, and body position

Somatic nervous system

controls voluntary movements under orders from the cerebral cortex

Limbic system

controls emotion and mood

The basal nuclei (also called basal ganglia) are

are deep clusters of gray matter that help control and fine-tune movement.

The thalmus, basal nuclei, and cerebellum are all apart of the

motor coordination loop

Limbuc system

mood, emotion and memory

Stoke or Cerebral Vascular accident(CVA)

is caused by disruption of blood flow to a portion of the brain due to either hemorrhage or blood clot

Transient Ischemic Attack (TIA)

It happens when there is a temporary blockage of blood flow to the brain, but the blockage resolves before permanent damage occurs.

huntingtins disease

a progressive disorder causing deterioration of neurons in the basal nuclei and eventually of the cerebral cortex
