How do the images appear on the retina?
Light enters the eye through the cornea and lens, which focus the image on the retina at the back of the eye. The retina contains photoreceptor cells (rods and cones) that convert the light signals into electrical impulses. These impulses are then processed by the brain to create the images we see.
Which cranial nerves conduct the sensory and motor impulses of the eye?
The Optical nerver or the Second Cranial nerve controls and relays information absorbed through the rods and cones of the eye. Eye movements (eye muscles), however, are controlled by several other cranial nerves including the Oculomotor, Abducens, and Trochlear nerves.
What carries impulses from the retina to the brain?
The optic nerve carries impulses from the retina to the brain. It is responsible for transmitting visual information from the eye to the brain for processing.
What lobe has impulses traveling down the cranial nerve 2?
impulses travel down cranial nerve 2 to what lobe
How are brain impulses transmitted when seizure activity occurs?
During seizure activity, abnormal electrical impulses in the brain cause excessive, uncontrolled firing of neurons. This leads to a cascade of hyperexcitability spreading through the brain, resulting in seizures. The transmission of these electrical impulses can disrupt normal brain function and cause the characteristic symptoms of a seizure.
What is the definition of optic nerve?
Each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye.
What nerve is carrying impulses from the eye to the thalamus?
The optic nerves carry the impulses from the eyes to the visual area of the thalamus.
Neural impulses are first sensed by the?
the optic nerve in your eye
The nerve carrying impulses from the eye to the thalamus is the nerve.?
optic....................
The nerve carrying impulses from the eye to the thalamus is the what nerve?
Optic Nerve
Which part of the eye has cells that change light energy to nerve impulses?
The retina
What carries nerve impulses from the eye to the brain?
The optic nerve
How do horses see?
Exactly the same way as humans do, light enters their eye through the pupil, the light is then focused onto the retina, which is at the back of the eye, by the lens. The photo receptive cells, called rods and cones, turn the light stimulation in electrical impulses, which is brought to the brain by the optic nerve. The electrical impulses are then perceived by the brain as images.
How do eye cells communicate with muscle cells?
The eye cells transmit nerve impulses to the brain, which translates the signal and transmits nerve impulses to the muscles. Information from sensory organs, including the eyes, ears, tongue, and skin, are transmitted by nerve impulses directly to the brain. The brain acting as the control center of the body interprets the nerve impulses. It then sends out different nerve impulses to other cells of the body if a response to the sensory signals is needed.
Is it true that the motor impulses leave the dorsal horn of the spinal cord?
No, motor impulses typically leave the spinal cord via the ventral horn. The dorsal horn is responsible for receiving sensory input.
Where do nerve impulses leave the neuron?
Nerve impulses are transmitted down the axon and leave the neuron via the terminal bouton at the synaptic interface, releasing neurotransmitters into the synaptic cleft to affect the post-synaptic cell..
What part of the eye receives impulses from the cones and rods?
i think the hippocampus.
