1. Cerebral Hemisphere
a. The cerebrum is broken up into two hemispheres. Each hemisphere is divided into frontal, parietal, temporal, and occipital lobes (Starkey, Brown, & Ryan, 2011).
2. Cerebellum
a. The cerebellum provided the functions necessary to maintain balance and coordination (Starkey, et al., 2011).
3. Cerebrum
a. The cerebrum is responsible for controlling the body’s primary motor function, sensory information, and cognition (Starkey, et al., 2011).
4. Brain Stem
a. The brain stem is formed by the medulla oblongata and the pons (Starkey, et al., 2011).
b. Its main functions are to relay information to and from the central nervous system (CNS), and control the involuntary system of the body (Starkey, et al., 2011).

Pia mater
a. The pia mater is the innermost meningeal layer, encasing the brain and the spinal cord (Starkey, et al., 2011).
13. Diencephalon
a. The diencephalon is formed by the thalamus, hypothalamus, and the epithalamus (Starkey, et al., 2011).
b. Its primary purpose is to act as a processing center for conscious and unconscious brain input (Starkey, et al., 2011).
14. Common carotid artery
a. Each common carotid artery diverges to form an internal carotid artery and an external carotid artery (Starkey, et al., 2011).
b. The internal supplies blood to the center of the cranium in order to supply the entire brain with blood; the external supplies blood to the head and neck, with the exception of the brain (Starkey, et al., 2011).
15. Circle of Willis
a. The circle of Willis is a section of the circulatory system that includes the internal carotid arteries and the vertebral arteries, as they converge to form a circulation network (Starkey, et al., 2011).
b. This circle is used, so that if a cranial artery is obstructed, the design of the circle permits partial blood supply to the area (Starkey, et al., 2011).
16. Vertebral artery
a. The vertebral artery is one of two key arteries located along the back of the neck that carry blood from the heart to the brain, spine, and neck muscles (AnatomyExpert,
Yes, the stylomastoid artery enter the stylomastoid foramen and supplies the external acoustic meatus, mastoid cells, semicircular canals, stapedius muscle, and vestibule. b. Of what artery is it most commonly a branch?
This is the artery that transfers blood to the lungs. The last major artery in the duck, is the Femoral which transfers blood to the legs and thighs which are used as transportation for
It sends information for sleep, hearing, taste, and even eye movement. Corpus Callosum: The corpus callosum connects both hemispheres of the brain and allows them to relay messages between one another. People who have a severed corpus callosum can essentially function as 2 different people at the same time, with the left half of their body performing one task, and the right half another. Frontal Lobe: As the largest lobe in our brain, this lobe play a significant role in personality and impulse control.
Forebrain #3 The section I chose is the forebrain which controls the higher functions of the brain, such as thinking, decision making, and dreaming. I chose forebrain #3 which consists of the occipital lobes, parietal lobes, and the somatosensory cortex. The occipital lobes is the visual processing center of the brain containing most of the region of the visual cortex. The occipital lobes are involved in many functions including visual perception, color recognition, reading, comprehension, depth perception, and recognition of object movement.
Firstly, the human brain is a complex organ that commands a variety of different functions within the human body. One specific function of the human
The first part of the brain that I had chosen that helps carry out the activity I had chosen was the cerebellum. The cerebellum plays a major part in being able to accomplish taking a shower. The cerebellum makes taking a shower possible because this part of the brain maintains your balance and muscle coordination. For example, if you were taking a shower you would need to keep your balance while washing yourself.
The brain is the most complex and magnificent organ of the human body. It controls the muscle movements, the secretions of glands,breathing and internal temperature. Every creative thought, feeling, and plan is developed by the brain. The brain acts as the body’s control center. The human brain can be divided into the forebrain, mid-brain and hind-brain.
Parts of the brain and their functions: the frontal brain with controls the higher mental processes. The midbrain, which controls emotions, motivations and the limbic system. The hindbrain which controls movement, and lower mental functions. 3. Split brain: when the corpus callosum is split it destroys the connection between the left and right side of the brain.
Furthermore, the regulation of the respiratory center can be modified in response to inputs from other brain regions, receptors in the peripheral nervous system, and other factors (chemoreceptors, voluntary control, etc.) in order to preserve the homeostasis of breathing. The respiratory center comprises of dispersed clusters of neurons located near the brain stem that modify the breathing muscles of the thorax by transmitting nerve impulses from centers in the brain which signals either contraction or relaxation (absence of nerve impulses). The respiratory center can be divided into two sections: the medullary respiratory center in the medulla oblongata and the pontine respiratory group (or pneumotaxic area) in the pons. The medullary respiratory
Blood vessels names are determined by their blow flow (away from the heart is artery; vein is towards the heart). If they connect arteries and veins then they are called capillaries and if an organ is receiving or returning the blood then the organ’s name is a part of the blood vessel’s name. Circle of Willis is a looped network (anastomosis) of arteries at the base of the brain. Branches of the internal carotid arteries form the front of the circle and branches of the posterior cerebral arteries form the back of the circle, with smaller arteries, collectively called the communicating arteries, branching from them. The circle of Willis is “a unique vascular structure in the body that provides an extended safety net of redundancy for the brain’s blood supply; the
The cerebellum controls things like procedural memory, motor learning, and classical conditioning. Things that are day to day movements such as blinking your eye is controlled by your cerebellum; you perform the movement without realizing it, because you are used to it (lumen). The brain is a very complex organ that is being utilized all-day and even while you are asleep and processing important
The forebrain is cut into two, called the Telencephalon, and the diencephalon (sensory and autonomic). The first is the biggest part of brain, also named the Cerebrum. It controls our thoughts and actions. The Cerebrum itself is divided into four Lobes. The Frontal Lobe, Parietal Lobe, Occipital Lobe and the Temporal Lobe.
On the other hand, internal thoracic artery (ITA) arises as a major branch of the subclavian artery in the neck, it passes posterior to the clavicle and the large veins in the region and anterior to the pleural cavity.
The cerebellum is a structural unit of the central nervous system that plays a major role in controlling and coordinating movement. Also, it is principally responsible for adaptation and learning by correcting error process and making accurate movement through the trails. The corrections can be made both during the course of the movement and as a form of motor learning when the correction is stored. Learning to throw a ball at a target while wearing prism spectacles or without it would be an example of adaption learning. When subjects without glasses throws a ball in the direction of the target, the ball almost hit the target.
The cortex is divided into four different lobes, the frontal, parietal, temporal, and occipital. It is responsible for higher thought processes including speech, and decision making which respectively is the equivalent to
