It bends or refracts light rays entering the eyes. C. It is the site of attachment for the extraocular muscles. D. It helps to maintain the shape of the eye. Answer Key: B Question 2 of 20 1.0 Points The border between the transparent edge of the cornea and the white of the fibrous sclera is the: A. pupil. B. anterior chamber.
The tunica vasculosa of the eye includes all of the following except: (a) the cornea; (b) the iris; (c) the choroid; (d) chromatophores; (e) the ciliary body. 11. Outer hair cells of the cochlea have their microvilli embedded in: (a) the vestibular membrane; (b) the tectorial membrane; (c) the basilar membrane; (d) the cupula; (e) the vitreous body. 12. ___ cells of the retina are inhibited by glutamate in the dark, but excited in the light when glutamate secretion stops.
White matter is made up of myelinated axons; the white of myelin is where White matter actually gets its name from. Gray matter on the other hand consists of neuronal cell bodies, dendrites, un-myelinated axons, axon terminals and neuroglia. It looks gray because there is little or no myelin in these areas and the Nissl bodies give off a gray color. The spinal cord has white matter which surrounds the gray matter making it look like a butterfly to some. 5.
Such as exposure to the sun will affect your skin color. A human’s skin contains two different layers and varies with thickness. Now the dermis contains down growths from the epidermis like hair follicles and glands. Glands produce the epidermis. It provides with five layers of skin such as located on the palm and soles.
This results in rods being able to detect objects in dim light and making it difficult for cones to detect color in dim light (Turley, 2011). Introduction: When the photoreceptor cells in the retina called rods and cones breakdown and die there is progressive vision loss and a person is said to have retinitis pigmentosa- an inherited disease of the retina (Learning about Retinitis Pigmentosa, 2012). “Retinitis Pigmentosa is the name given to a group of inherited eye diseases that affect the retina” (Learning about Retinitis Pigmentosa, 2012). The breakdown of rods and ones is common to all forms of this
It provides nutrients and serves to cushion the brain and therefore protect it from injury. As this fluid gets absorbed, more is produced from the choroid plexus, a structure located in the ventricles. A brain tumor can cause a build-up or blockage of CSF. Four Ventricles of the brain are connected cavities within the brain, where cerebrospinal fluid is produced. Four Ventricles of the brain are connected cavities within the brain, where cerebrospinal fluid is produced.
Priscilla Sims 1. Compare and contrast the functions of each tissue type. Why do some areas of our body have stratified squamous epithelium and other areas have simple squamous epithelium? There are four basic tissue types in the human body: epithelial, connective, muscle and neural. The epithelial tissue covers the body surfaces and lines the cavities and tubular structures and serves essentials functions.
b. Has collagen and elastic fibers, but not reticular like name suggests. c. Skin Color is determined by 3 pigments: melanin, carotene, and hemoglobin. 1) All races have about the same number of melanocytes, but produce different quantities of melanin in the melanocytes. Melanin is brownish-black 2) Carotene is yellow-orange 3) Hemoglobin is a red pigment found in the red blood cells of the blood.
These concepts don’t always work in isolation, and are best tested by having you look at objects and describe them. 4: Styles of art. Can you distinguish between representational, abstract, realistic, and nonobjective art? Do you know what it means to give describe the content (iconography) of a work? How about to discuss the form of a
