What are the subparts of the brain?

What are the subparts of the brain?

The brain has three main parts: the cerebrum, cerebellum and brainstem.

  • Cerebrum: is the largest part of the brain and is composed of right and left hemispheres.
  • Cerebellum: is located under the cerebrum.
  • Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.

What is the outside of the brain called?

The cerebrum has billions of neurons and glia that form the cerebral cortex, its outermost layer. This is commonly known as gray matter. Connection fibers between neurons beneath the surface of the brain are called white matter. The cerebellum, or hindbrain, handles fine motor movements, balance, and posture.

What is the anatomical description of the brain?

The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

What part of the brain controls thumbs?

Experts have discovered that people who use touchscreen phones on a daily basis have a larger and more powerful somatosensory cortex – the area at the centre of the brain which controls the thumbs.

What part of the brain controls happiness?

limbic cortex
Imaging studies suggest that the happiness response originates partly in the limbic cortex. Another area called the precuneus also plays a role. The precuneus is involved in retrieving memories, maintaining your sense of self, and focusing your attention as you move about your environment.

What is the most protected part of the brain?

cranium
The brain is housed inside of a bony covering called the cranium. The cranium protects the brain from injury and along with the bones that protect the face are called the skull.

What is the most important organ?

brain
Anatomy & Function The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.

What part of the brain controls fine motor skills?

cerebellum
The cerebellum is located behind the brain stem. While the frontal lobe controls movement, the cerebellum “fine-tunes” this movement. This area of the brain is responsible for fine motor movement, balance, and the brain’s ability to determine limb position.

Are there any reflexes in the cerebral peduncles?

The pupillary reflex (adjustment for light intensity), accommodation reflex (focus on near or far away objects), and startle reflexes are among the many reflexes relayed through this region. Forming the anterior region of the midbrain, the cerebral peduncles contain many nerve tracts and the substantia nigra.

Which is part of the brain is parallel to the ground?

•Coronal: taken in the plane of the face •Sagittal: taken in the plane dividing the 2 hemispheres, perpendicular to the coronal plane •Horizontal (axial transverse): taken parallel to the rostral-caudal axis of the brain; so if an individual is standing upright, these sections are parallel to the ground

Where does most processing of the cerebrum take place?

Most of the processing of the cerebrum takes place within the cerebral cortex. The bulges of cortex are called gyri (singular: gyrus) while the indentations are called sulci (singular: sulcus). Deep to the cerebral cortex is a layer of cerebral white matter.

Where are the pons located in the brain?

The pons bulges anteriorly from the upper part of the medulla. Within the pons are two respiratory centers that work with those in the medulla to produce a nor-mal breathing rhythm. The many other neurons in the pons ( pons is from the Latin for “bridge”) connect the medulla with other parts of the brain.
