Why is the gray matter concentrated in the cerebrum?
The gray matter in the cerebrum is concentrated in the outer layer called the cerebral cortex, which is responsible for higher brain functions such as thinking, memory, and perception. This concentration allows for complex processing of information and integration of sensory inputs from various parts of the body.
What forms the outer layer of the cerebral cortex?
The outer layer of the cerebral cortex is formed by gray matter, which consists of nerve cell bodies, dendrites, and synapses. This layer is crucial for processing information in the brain, including sensory perception, motor function, and higher cognitive functions.
Where are receptors for somatic sensations located?
Receptors for somatic sensations are located in the skin, muscles, joints, and internal organs. These receptors detect sensations such as touch, pressure, temperature, and pain, and send signals to the brain via sensory nerves.
How does cerebral cortex differ from the rest of the cerebrum?
The cerebral cortex is the outermost layer of the cerebrum, composed of gray matter, and is responsible for higher cognitive functions such as perception, decision-making, and motor control. In contrast, the rest of the cerebrum, which includes the underlying white matter and various subcortical structures, primarily facilitates communication between different brain regions and processes information. The cortex's intricate folding increases its surface area, allowing for more neurons and enhancing its functional capabilities compared to the deeper structures of the cerebrum.
Layer of nerve tissue made up of sensory neurons that respond to light?
The retina is the layer of nerve tissue in the back of the eye that contains sensory neurons called photoreceptors. These photoreceptors, specifically rods and cones, respond to light and convert it into electrical signals, which are then transmitted to the brain via the optic nerve, allowing us to perceive visual information.

This concentration allows for complex processing of information and integration of sensory inputs from various parts of the body.
Largest area of the brain?
The cerebral cortex, which is the outer layer of the brain, is the largest area of the brain in terms of surface area and plays a key role in higher brain functions such as thinking, planning, and processing sensory information.
What forms the outer layer of the cerebral cortex?
The outer layer of the cerebral cortex is formed by gray matter, which consists of nerve cell bodies, dendrites, and synapses. This layer is crucial for processing information in the brain, including sensory perception, motor function, and higher cognitive functions.
What layer of skin contains sensory receptors for touch?
The Dermis layer contains the sensory nerve fiber, so it is the Dermis layer that contains sensory receptors for touch.
The part of the integumentary system that contains sweat glands and sensory receptors?
The layer of the integumentary system that contains sweat glands and sensory receptors is the dermis. This layer is located beneath the epidermis and plays a crucial role in regulating body temperature and providing sensory information to the brain.
What part of brain has an outer layer called the cortex?
cerebrum
How many layer of cerebrum?
6 layers 1- molecular layer 10% 2-external granular layer 10% 3-external pyramidal layer 30% 4-internal granular layer 10% 5-internal pyramidal layer 20% 6-multiform layer 20%
What is the outer layer of the cerebrum called?
The outer layer of the cerebrum is called the cerebral cortex. It plays a key role in higher brain functions such as thinking, memory, and voluntary movement.
What is the sensory tunic?
The sensory tunic is a layer of cells in the eye that contains photoreceptor cells (rods and cones) responsible for detecting light and transmitting visual information to the brain. It is located in the innermost layer of the eye, adjacent to the retinal pigment epithelium.
What makes outer layer of cerebrum grey in colour and inner layer to be white in colour?
The outer layer gets dusty, while the inner layer is protected from dust.
Which layer of the skin is compose of thousands of sensory receptors?
The dermis layer of the skin is composed of thousands of sensory receptors, including touch receptors, temperature receptors, and pain receptors. These receptors help you to feel sensations and respond to your environment.
Which part of the brain contains the cerebral cortex which plays an important role in functions such as thought voluntary movement language reasoning and perception?
The cerebral cortex is located in the outer layer of the brain known as the cerebrum. It is responsible for processing sensory information, thoughts, voluntary movements, language, reasoning, and perception. The cerebral cortex is divided into four lobes: frontal, parietal, temporal, and occipital.
