RESPONSE ONE: Research
The Cerebrum consists of the frontal lobe, parietal lobe, occipital lobe, temporal lobe and the insula. All five of these lobes have their own set of unique functions. Today, I will be going in depth about the frontal lobe, which is located directly behind the frontal bone, and superior to the eyes. According to the Cleveland Clinic, the frontal lobe takes up between 25% and 40% of the brain’s cerebral cortex and is composed of neurons and glial cells. The frontal lobe is responsible for our conscious, abstract thought; explicit or declarative memory; cognitive and emotional processes such as mood, motivation, foresight, planning, decision making, emotional control, and judging socially appropriate behavior; and in speech production (Saladin, 2024). Anything a person does that involves thinking or a conscious action, relies heavily on the frontal lobe.
The frontal lobe can be divided into two main areas: the motor cortex and the prefrontal cortex. The main function of the motor cortex is to control voluntary movement like writing, expressive language and ocular movement. Located in the front part of the frontal lobe is the prefrontal cortex, it is considered the ultimate expression of human brain development, and acts as a mediator between cognition and feelings through executive functions (CogniFit & Cognifit, 2024).
Critical Thinking
The frontal lobe is the slowest part of the brain to mature, continuing to develop until a person reaches their mid-twenties. This should be reassuring to all of us in our twenties that it’s okay not to have life figured out just yet, it might be because our frontal lobes are not quite done forming! Researching the frontal lobe has provided clarity as to why even the smallest bit of damage can be detrimental to cognitive functions. I can remember my mother getting upset with my brother and I when she would see us riding our bikes with no helmets on. Since the frontal lobe is most prone to concussions and traumatic brain injuries, I can see why helmet safety is always encouraged. Whether it’s for sports or for bike riding, helmets are extremely important and can prevent long term brain injury or even death.
REPSPONSE 2 :Cranial Nerves
Research
What are the 12 cranial nerves and their functions?
The 12 nerves are, the olfactory bulb 1, optic nerve 2, oculomotor nerve 3, trochlear nerve 4, trigeminal nerve 5, abducens nerve 6, facial nerve 7, vestibulocochlear nerve 8, glossopharyngeal nerve 9, vagus nerve 10, hypoglossal nerve 11, and lastly, accessory nerve 12. All these 12 nerves have a unique and very important purpose and function. For example, the olfactory nerve transmits information regarding a person’s sense of smell to the brain. The optic nerve transmits information to the brain regarding a person’s vision. The oculomotor nerve helps control muscle movements of the eyes. The trochlear nerve also has a role in eye movement. The trigeminal nerve is the largest cranial nerve and has both motor and sensory functions. The abducens nerve also helps control eye movements. The facial nerve also has both motor and sensory functions. The vestibulocochlear nerve helps with a person’s hearing and balance. The glossopharyngeal nerve possesses both motor and sensory functions. The vagus nerve has a range of functions, providing motor, sensory, and parasympathetic functions. The accessory nerve provides motor function to some muscles in the neck. The hypoglossal nerve is a motor nerve that supplies the tongue muscles. It originates in the medulla. (Johnson, s. 2022, June 5). Here are some fun facts about the nerves:
The vagus nerve is the longest cranial nerve as it starts in the medulla — the bottom part of the brain — and extends to the abdomen.
The shortest cranial nerve is the trochlear nerve, as it has the lowest number of axons. The twelve cranial nerves are a group of nerves that start in the brain and provide motor and sensory functions to the head and neck. Each cranial nerve has unique anatomical characteristics and functions. Doctors can identify neurological or psychiatric disorders by testing cranial nerve functions. (Johnson, s. 2022, June 5)
Did you know that 4 of the cranial nerves are concerned exclusively with the eyes ( 2, 3, 4, 6). (Saladin 2024).
Critical Thinking
I personally found this research super interesting. I love learning about the body and how everything is all connected. I find it fascinating how everything works and that 1 small thing has such a big purpose in our bodies. For example, looking at pictures of all the nerves, you can tell that everything is connected and they each have an important role in our bodies but what blows my mind is how some of them are connected to 1 specific part of our bodies yet do completely different things, so many things are happening inside of our bodies and we don’t even realize or feel it.
