Purkinje Fibers: Purkinje fibers are clearly identified on the inner ventricular walls of the heart, just underneath the endocardium in an area named the subendocardium. The Purkinje fibers are functional conducting fibers, that are comprised of electrically excitable cells and are larger than the normal myocardial fibers. The Purkinje fibers are of the huge number …

Thalamus : Anatomy, Location & Function
Thalamus: The thalamus is a huge volume of gray matter within the dorsal part of the diencephalon of the brain, separated into two walnut-sized parts. Both of the thalami are found deep in the center of the brain, between the midbrain and the cerebral cortex. The thalamus is a vital structure with several functions such …
Cerebellum : Anatomy, Location & Function
Cerebellum: The cerebellum is a major feature of the hindbrain. The cerebellum performs an important part in motor control. It may additionally be associated while some cognitive functions such as attention and language as sound as in regulating fear and pleasure responses. The cerebellum resembles not initiate movement, but provides to precision, coordination, and accurate …
Brain Stem : Anatomy, Location & Function
Brain Stem: The brainstem also has known as brain stem is the back part of the brain, joining and structurally continuous with the spinal cord. In the brain, brainstem comprises the midbrain, the pons, and the medulla oblongata. The brain stem performs the motor and sensory innervation to the face and neck through the cranial …
Pineal Gland : Anatomy, Location & Function
Pineal Gland: The pineal gland, also known as the epiphysis cerebri, epiphysis or third eye is a small endocrine gland in the brain. The pineal gland produces melatonin, a serotonin-derived hormone that changes sleep patterns in both circadian and the periodical cycles. The pineal gland further performs a function in the regulation of female hormone …
Pituitary Gland : Parts, Location & Function
Pituitary Gland: The pituitary gland also known as hypophysis gland, is an endocrine gland approximately the size of a pea and measuring 0.5 grams and the pituitary gland located in a bony hollow, just behind the bridge of your nose. .The pituitary gland rests upon the hypophysial fossa of the sphenoid bone in the middle …
Frontal Lobe : Anatomy, Location & Function
Frontal Lobe: The frontal lobe is the largest of the four major lobes of the cerebral cortex in the brain. The frontal lobe, located at the front of the brain, of each cerebral hemisphere in front of the temporal lobe and the parietal lobe. The frontal lobe is separated from the parietal lobe by a …
Temporal Lobe : Anatomy, Location & Function
Temporal Lobe: The brains contain four lobes in the cortex, including the occipital, parietal, temporal, and frontal lobes. The temporal lobe located just beneath the lateral fissure and crisscrossing both fissures of the brain. This vital structure of the temporal lobe supports process the sensory input, including pain and the auditory stimuli. It further helps …
Parietal Lobe : Anatomy, Location & Function
Parietal Lobe: The brain is made of the four lobes of the cerebral cortex in the brain. The parietal lobe is the major lobe in the brain. The parietal lobe is located over the temporal lobe and back of the frontal lobe and the central sulcus. The parietal lobe integrates sensory information with numerous modalities, …
Occipital Lobe : Anatomy, Location & Function
Occipital Lobe: The occipital lobe is one of the four lobes of the cerebral cortex in the brain. The occipital lobe is positioned at the back portion of the brain and is associated with understanding visual stimuli and information. The primary visual cortex region is Brodmann area 17, usually termed V1 (visual one).V1 is placed …
Pons : Anatomy , Location & Function
Pons: Pons, a portion of the brain lying inferior to the midbrain, above the medulla oblongata and anterior to the cerebellum. The pons is a broad, horseshoe-like shaped mass of transverse nerve fibers that connect between the cerebrum and cerebellum. The pons measures roughly 2.5 centimeters (0.98 in) in length. The pons of the brainstem …
Corpus Callosum : Anatomy, Location & Function
Corpus Callosum: The brain is divided into the right and left hemisphere. Corpus callosum is a thick band of nerve fibers that connects the right and left hemisphere of the brain, allowing for communication between both hemispheres. The bundle of nerve tissue of corpus callosum carries over 200 million axons by rough estimate. This neural …
