Language Areas Animation

By: Administrator, Views: 9763

Specific language areas of the brain. Many cortical (and non-cortical!) regions are involved in language processing. The primary language pathway begins in Wernicke’s area (posterior temporal lobe), which receives information from the auditory and visual cortices and assigns meaning (= lang...

Respiratory system: nose pharynx larynx trachea bronchi lungs Respiratory system’s primary function: Furnish oxygen (O2) for use by individual tissue cells and take away their gaseous waste product, carbon dioxide (CO2), through act of respiration. External respiration Lungs are vent...

Functional zones in a mitochondrion

By: HWC, Views: 4584

A mitochondrion has a double membrane system. The outer membrane faces the cytoplasm. The inner membrane divides the organelles interior into two compartments. The enzymes that carry out the second stage reactions are in the semifluid matrix inside the inner compartment. Embedded in the ...

The cavernous sinuses are located within the middle cranial fossa, on either side of the sella turcica of the sphenoid bone (which contains the pituitary gland). The cavernous sinuses, a rich plexuses of veins that surround the internal carotid arteries, lie lateral to the pituitary fossa. Ant...

Chromosome structural organization/ Mechanisms for chromosome movement Animation

By: HWC, Views: 2753

How the chromosome is organized. At metaphase, the chromosomes are duplicated and are at their most condensed. In each chromosome, two identical sister chromatids are held together at a constricted region called the centromere. When a chromosome is condensed, interactions among chromosomal ...

Nerve Impulse Transmission Animation

How nerves transmit impulses. Stimulation of a nerve occurs at a receptor. Sensory receptors Specialized to specific types of stimulation such as heat, cold, light, pressure, or pain. React by initiating a chemical change or impulse. All-or-none principle Means that no transmission occ...

Sister chromatids of a metaphase chromosome animation

By: HWC, Views: 4655

At metaphase, the chromosomes are duplicated and are at their most condensed. In each chromosome. two identical sister chromatids are held together at a constricted region called the centromere. When a chromosome is condensed, interactions among chromosomal proteins keep loops of DNA tightly ...
