neurotic much?
These are branching extensions of the neuron that receive signals from other neurons or sensory receptors and conduct impulses toward the soma.
What are dendrites?
This part of the brain is a coordination center responsible for balance, posture, and fine motor control. it coordinates voluntary movements and maintains equilibrium.
What is the cerebellum?
This plane divides the body into superior and inferior portions.
What is the transverse plane?
This layer of skin is located beneath the dermis and consists primarily of adipose tissue (fat cells). This layer provides insulation, cushioning, and energy storage.
What is the hypodermis?
These types of receptors are found in the retina and respond to light stimuli.
What are Photoreceptors?
The peripheral nervous system is comprised of all of the nerves in the body whereas the central nervous system is comprised of this and this.
What are the brain and spinal cord?
This part of the brain helps regulate body temp, hunger, and thirst. It also controls hormone release from the pituitary gland.
What is the hypothalamus?
Blood vessels in the skin widen to help regulate temperature through this process.
What is vasodilation?
These are specialized cells in the epidermis that produce melanin, a pigment that gives skin its color and provides protection against ultraviolet (UV) radiation from sunlight.
What are melanocytes?
The opening in the center of the iris that regulates the amount of light entering the eye.
What is the pupil?
This neurotransmitter controls skeletal muscle actions in both the central and peripheral nervous systems. Deficiency of this neurotransmitter is associated with conditions like myasthenia gravis.
What is acetylcholine?
This part of the brain is the largest and is responsible for conscious thought, memory, voluntary movement, and sensory perception.
What is the cerebrum?
A group of cells make up this and a group of them make up organs.
What are tissues? (IK u mad at me. not kiara tho. tiv <3)
These cells are located in the deepest layer of the epidermis and are responsible for producing new epidermal cells through cell division. As new cells are produced, older cells are pushed toward the surface.
What are basal cells?
This is the transparent front part of the eye that helps focus light aka the first lens.
What is the cornea?
These neurons transmit impulses from sensory receptors to the central nervous system.
What are afferent/sensory neurons?
This neurotransmitter regulates mood, sleep, and appetite. Imbalances in this are associated with depression or anxiety.
What is serotonin?
The diaphragm separates the thoracic cavity (lungs & heart) and this cavity.
What is the abdominal/abdominopelvic cavity?
This layer of skin protects the underlying tissues from physical damage, pathogens, an UV radiation. This layer is also where melanin is produced, it prevents water loss, produces vitamin D precursors, and provides sensation.
What is the epidermis?
This is the colored part of the eye that contains muscles to control the pupil size. It constricts the pupil in light and dilates in the dark.
What is the iris?
These cells produce myelin sheaths around axons in the central nervous system.
What are oligodendrocytes?
The brainstem is composed of these three components.
What are the midbrain, pons, and medulla oblongata?
When talking about membranes, parietal refers to the covering of the inner wall whereas visceral refers to covering these.
What are organs?
e.g. visceral pleura covers the lungs and visceral peritoneum covers the internal organs.
This part of the skin contains connective tissue, blood vessels, hair follicles, sebaceous glands, and sudoriferous glands.
What is the dermis?
The blind spot of your eye is when this is interrupted by the optic nerve. You can't see anything because there is an absence of rods and cones (photoreceptors).
What is the retina?
These cells produce myelin sheaths around neurons in the peripheral nervous system.
What are schwann cells?
This neurotransmitter is involved in arousal, attention, and the fight-or-flight response.
What is norepinepherine?
This term refers to the arm region.
What is brachial?
This really long and annoying word refers to glands that produce sweat, which helps regulate body temperature through evaporation and removes some waste products.
What are sudoriferous glands?
This is the transparent structure of the eye that focuses light onto the retina.
What is the lens?
These star-shaped cells provide structural support and help regulate the chemical environment around the neurons.
What are astrocytes?
This is composed of the hypothalamus and thalamus.
What is the diencephalon?
These refer to damage from heat, radiation, chemicals, and electricity that involve the entire thickness of the skin, including the epidermis, dermis, and hypodermis. These burns destroy all layers of skin and require medical intervention.
What are third-degree burns?
These types of receptors detect deep pressure and vibration.
What are Lamellated Corpuscles?
This is the white, tough outer layer that provides structure and protection, filled with aqueous and vitreous humor.
What is the sclera?
