The structure And duty Of The human Brain

*
The mind structure is written of three key parts: the forebrain, midbrain and hindbrain, each with multiple parts.

You are watching: What is the largest part of the hindbrain

Forebrain

The Cerebrum: additionally known together the cerebral cortex, the cerebrum is the largest part of the human brain, and it is connected with higher mind function such together thought and also action. Nerve cells comprise the gray surface, which is a little thicker 보다 our thumb. White nerve yarn beneath the surface bring signals between nerve cells in other parts that the mind and body. That wrinkled surface increases the surface area, and also is a six-layered structure found in mammals, called the neocortex. It is divided into four sections, called “lobes”. Lock are; the frontal lobe, the parietal lobe, the occipital lobe and the temporal lobe.

Functions the The Lobes:

Frontal Lobe – The frontal lobe lies just beneath ours forehead and is linked with our brain’s capacity to reason, organize, plan, speak, move, make facial expressions, serial task, difficulty solve, manage inhibition, spontaneity, initiate and self-regulate behaviors, salary attention, remember and control emotions.

Parietal Lobe – The parietal lobe is located at the top rear of ours brain, and controls our facility behaviors, consisting of senses such together vision, touch, human body awareness and spatial orientation. That plays vital roles in integrating sensory details from various parts of our body, knowledge of numbers and also their relations, and also in the manipulation of objects. Sections are associated with our visuospatial processing, language comprehension, the capability to construct, human body positioning and movement, neglect/inattention, left-right differentiation and self-awareness/insight.

Occipital Lobe – The occipital lobe is located at the ago of our brain, and is linked with our visual processing, such together visual recognition, visual attention, spatial analysis (moving in a 3-D world) and visual perception of human body language; such as postures, expressions and gestures.

Temporal Lobe – The temporal lobe is located near ours ears, and also is associated with processing our perception and recognition of auditory stimuli (including our capacity to focus on one sound amongst many, choose listening to one voice among many in ~ a party), comprehending spoken language, linguistic memory, intuitive memory and language manufacturing (including fluency and word-finding), basic knowledge and also autobiographical memories.

A deep furrow divides the cerebrum right into two halves, known as the left and right hemispheres. And, while the two hemispheres look nearly symmetrical, every side appears to function differently. The appropriate hemisphere is thought about our an imaginative side, and the left hemisphere is thought about our reasonable side. A bundle the axons, dubbed the corpus callosum, associate the two hemispheres.

Midbrain

The midbrain is located below the cerebral cortex, and over the hindbrain place it near the facility of the brain. The is made up of the tectum, tegmentum, cerebral aqueduct, cerebral peduncles and several nuclei and fasciculi. The primary role of the midbrain is to act as a sort of relay station for our visual and also auditory systems. Parts of the midbrain referred to as the red nucleus and also the substantia nigra are associated in the manage of human body movement, and also contain a large number that dopamine-producing neurons. The degeneration that neurons in the substantia nigra is associated with Parkinson’s disease. The midbrain is the smallest an ar of the brain, and also is situated most centrally within the cranial cavity.

Limbic mechanism – the limbic mechanism is regularly referred to together our “emotional brain”, or ‘childish brain’. The is found hidden within the cerebrum and also contains the thalamus, hypothalamus, amygdala and also hippocampus.

Thalamus – the primary duty of the thalamus is come relay sensory details from various other parts the the brain to the cerebral cortex

Hypothalamus – the primary role of the hypothalamus is to regulate various functions of the pituitary gland and endocrine activity, as well as somatic features e.g.body temperature, sleep, appetite.

Amygdala – the primary function of the amygdala is to it is in a vital processor for the senses. Connected to the hippocampus, the plays a function in emotionally laden memories and also contains a huge variety of opiate receptor sites that are implicated in rage, fear and also sexual feelings.

Hippocampus – the primary function of the hippocampus is memory forming, organizing and also storing information. The is an especially important in forming brand-new memories, and connecting emotions and senses, such as smell and also sound, come memories.

Pituitary Gland – the primary role of the pituitary gland is an essential link between the concerned system and also the endocrine system. That releases plenty of hormones which affect growth, metabolism, sexual development and the reproduction system. It is linked to the hypothalamus and also is about the size of a pea. The is situated in the center of the skull, simply behind the bridge of the nose.

Hindbrain

The Cerebellum – The cerebellum, or “little brain”, is similar to the cerebrum v its 2 hemispheres and also highly urgently surface. That is associated with regulation and coordination the movement, posture, balance and cardiac, respiratory and also vasomotor centers.

Brain Stem – The brain stem is located beneath the limbic system. That is responsible for vital life features such together breathing, heartbeat, and also blood pressure. The mind stem is made of the midbrain, pons, and medulla.

Pons – The primary function of the pons is to serve as a bridge between various components of the worried system, consisting of the cerebellum and also cerebrum. Numerous important nerves that originate in the pons, such together the trigeminal nerve, responsible for feeling in the face, and also controlling the muscles that space responsible because that biting, chewing, and swallowing. It also contains the abducens nerve, which enables us come look from next to side and also the vestibularcochlear nerve, which enables to hear. As part of the brainstem, a section of the lower pons stimulates and also controls the strongness of breathing, if a ar of the upper pons to reduce the depth and also frequency the breaths. The pons is likewise associated through the manage of sleep cycles, and controls respiration and also reflexes. It is located over the medulla, listed below the midbrain, and also just in prior of the cerebellum.

Medulla – The primary role of the medulla is regulation our involuntary life sustaining functions such together breathing, swallowing and heart rate. As component of the mind stem, it also helps transfer neural message to and also from the brain and spinal cord. The is located at the junction that the spinal cord and brain.
