What are the 4 main parts of the human brain?

4 Main Parts of the Brain

  • Brainstem. involved in lower function tasks ( respiration, heart rate)
  • Midbrain. (Mesencephalon) most superior, located just below third ventricle.
  • Pons. (means bridge) below midbrain.
  • Medulla Oblongata. below pons.
  • Diencephalon. mean 2 brains, 3 parts.
  • Thalamus.
  • Hypothalamus.
  • Reticular Formation.

  • What are the six major parts of the brain?

    6 Major Parts of the Brain and What They Do

  • Lobes of the Brain. Frontal Lobes.
  • Motor Cortex and Somatosensory Cortex. Between the parietal and frontal lobes are two bands across the top of the brain from ear to ear.
  • Brain Stem.
  • The Limbic System.
  • Cerebrum.
  • Cerebellum.
  • What are the four main parts of your brain?

    Here is a brief overview of the four key parts of the brain:

  • Frontal lobe. Located in the front of the brain, this lobe is responsible for planning and organising incoming information.
  • Parietal lobe. Crucial in integrating sensory and visual information.
  • Temporal lobe.
  • Occipital lobe.
  • What are the four major divisions of the brain?

    The brain has four major divisions: 1) brainstem, including the medulla oblongata, pons, and midbrain; 2) cerebellum; 3) cerebrum; and 4) diencephalon. The diencephalon is further divided into the thalamus, hypothalamus, epithalamus, and ventral thalamus or subthalamus.

    What are the three major parts of the brain stem?

    The 3 parts of the brain stem are: the medulla, which is this section here; and then we have the pons; and we have the midbrain. So the medulla, pons, and the midbrain, those are the 3 parts of the brain stem.

    How many different parts of the brain are there?

    The human brain can be divided into three main parts: the forebrain, midbrain, and hindbrain: The forebrain includes the several lobes of the cerebral cortex that control higher functions.

    What are the four major regions of the brain?

    Four regions of the brain

  • Cerebrum. Executive functions of brain (consciousness). Divided into right and left hemispheres.
  • Diencephalon. Thalamus – relay station for cerebral cortex.
  • Cerebellum. Integrates cerebral motor instructions with proprioceptive.
  • Brain stem. Most basic, automatic survival behaviors.
  • What is the main function of the brain?

    The cerebellum sits at the back of your head, under the cerebrum. It controls coordination and balance. The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.

    What are the five lobes of the brain?

    The cerebrum is divided by a longitudinal fissure into 2 hemispheres, each containing 6 discrete lobes:

  • Frontal.
  • Parietal.
  • Temporal.
  • Occipital.
  • Insula.
  • Limbic.
  • What is the function of the brain?

    The brain is an organ that’s made up of a large mass of nerve tissue that’s protected within the skull. It plays a role in just about every major body system. Some of its main functions include: processing sensory information.

    What are the five components of a reflex arc?

  • Receptor – sense organ in skin, muscle, or other organ.
  • Sensory neuron – carries impulse towards CNS.
  • Interneuron – carries impulse within CNS.
  • Motor neuron – carries impulse away from CNS.
  • Effector – structure by which animal responds (muscle, gland, etc).
  • What separates the two hemispheres of the brain?

    Opening longitudinal fissure, the fissure which separates left and right cerebral hemispheres. The vertebrate cerebrum (brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure. The brain can thus be described as being divided into left and right cerebral hemispheres.

    What is the gray matter of the brain?

    Grey matter (or gray matter) is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and myelinated as well as unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.

    How the brain is protected?

    The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles. These bones protect the spinal cord.

    What is in the brain stem?

    The brain stem controls the flow of messages between the brain and the rest of the body, and it also controls basic body functions such as breathing, swallowing, heart rate, blood pressure, consciousness, and whether one is awake or sleepy. The brain stem consists of the midbrain, pons, and medulla oblongata.

    What are the 3 main parts of the brain and their functions?

    The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.

    What part of the brain is responsible for speech?

    Broca’s area or the Broca area /bro?ˈk?ː/ or /ˈbro?k?/ is a region in the frontal lobe of the dominant hemisphere, usually the left, of the hominid brain with functions linked to speech production. Language processing has been linked to Broca’s area since Pierre Paul Broca reported impairments in two patients.

    What is the function of the corpus callosum in the brain?

    Corpus callosum/the corpus callosum consists of about 200 millon axons that interconnect the two hemispheres. The primary function of the corpus callosum is to integrate motor, sensory, and cognitive performances between the cerebral cortex on one side of the brain to the same region on the other side.

    What is the role of the nervous system in the body?

    The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
