CEREBELLUM
The cerebellum mainly lies behind pons and midbrain. Functions of cerebellum are, when you are walking, the cerebellum continuously receives unconscious preconceptions from muscles, and joints. As well as receiving information from different senses based on that regulate. All the muscles contraction necessary to perform contraction necessary to perform your movements smoothly.
So, by doing that, its coordinates your balance and posture. It regulates the tone of your muscles by passively contracting. The muscles to ensure joints stability. And is also smoothens voluntary movements of muscles. When you write most of the fibers comes from the cerebral cortex since this is a voluntary movement. But these movements are able to be smooth and precise by the cerebellum engaging its fiber into the muscles necessary to stabilized the movements.
HYPOTHALAMUS
Hypothalamus is a small part of brain that contains a number of nuclei with a variety of functions.
HARMONES THAT ARE PRODUCED IN HYOPOTHALAMUS:
- THYROTROPIN-RELEASING HORMONE(TRH)
- CORTICOTROPIN-RELEASING HORMONE(CRH)
- GONADOTROPIN-RELEASING HORMONE(GnRH)
- GROWTH HORMONE-RELEASING HORMONE(GHRH)
- SOMATOS TATIN
- DOPAMINE
- VASOPRESSIN/ANTIDURATIC HORMONE(ADH)
- OXYTONIC
FUNCTIONS
Regulating bodily process
- Thirst and food intake
- Autonomic nerves system
- Biological circadian system
Body temperature
- Blood pressure
- Breast feeding
- Learning and memory
Sexual drive
- Emotional expression
BRAINSTEM
The brain stem is a stalk that leaves the bases of the brain to the spinal cord. It consists of many important pathways that run between the brain and spinal cord as well as pathways to the other areas like cerebellum.
It also has a large number of important nuclei, and is important for both survivals and proper cognitive functioning. It consists of three major divisions.https://yubloger.com/
The Medulla Oblong Ota
The Pons
The Midbrain
The medulla oblong Ota
The medulla oblong Ota simply called the medulla is the point where the brain stem connects to spinal cord, the medulla id essential for survival as it contains nuclei that ensures vital system like the cardiovascular and respiratory system and working properly. The medulla also contains nuclei that are responsible for a number of reflexive actions including vomiting, swallowing, coughing and sneezing.
The pons
The pons is a Latin word means bridge. And the pons is a large rounded structure resembling a rounded bridge that connects the medulla and the midbrain. The pons is home to a number of nuclei for cranial nerves and contains nuclei that deals with sensations from the head, face and mouth, hearing equilibrium and automatic functions like tear and saliva production.
The midbrain
One of the posterior sides of the midbrain we find four bumps representing two pared structures.
- Superior colliculi
- Inferior colliculi
The superior colliculi are involved in eye movements and visual processing, while the inferior colliculi are involved in auditory processing. the midbrain also contains the major dopamine-producing nuclei of the brain, the ventral tegmental area and substantia nigra.
