Final Exam Flashcards
What are the 4 major types of tissue?
Epithelium, connective tissue, muscle tissue, and nervous tissue
Where in the body can epithelium be found?
Nasal passages, esophagus, lungs, kidney, intestine, urinary tract (lines hollow organs that are in contact with outside environment)
What is the surface of epithelial tissue comprised of?
Epithelium and basement membrane
What are the arrangements of cell layers in the epithelial tissue?
Simple (single layer), Pseudostatified (one layer but appears not to be because nuclei do not line up), and stratified (consist of 2 or more layers)
What are the different cells’ shapes of epithelial tissue?
Squamous (thin for quick exchange), cuboidal (tall as they are wide and used for secretion or absorption), Columnar (tall and skinny and are more specialized for secretion or absorption), and Transitional (change size from squamous to cuboidal back and forth)
What are the two types of glands?
Endocrine (secrete hormones enter interstitial fluid
and then diffuse directly into bloodstream) and exocrine (secrete products into ducts that empty
onto the surface of a covering and lining epithelium
like skin or lumen of organ.)
What are the two types of exocrine glands?
Unicellular or multicellular
What are the 4 types of epithelial membranes?
Mucous, Serous, Cutaneous, Synovial
What do mucous membranes do within the body?
Lines body cavity that opens directly with the external environment. Produced via goblet cells. Has some enzymes within it to aid in digestion
What do serious membranes do within the body?
Line organs within a cavity. Made up of partial and visceral layers
What does the cutaneous membrane do within the body?
Covers entire body surface. Composed of epidermis and dermis.
What does the cutaneous membrane do within the body?
Covers entire body surface. Composed of epidermis and dermis.
What are synovial membranes used for within the body?
Lines cavities of freely moveable joints. Contains synovial fluid
What is connective tissue?
Most abundant and distributed in the body. Highly vascularized
What are the two elements of connective tissue?
Extracellular matrix and cells
What are the different types of cells found within connective tissue?
Fibroblasts (fat cells that secrete collagen)
Macrophages (engulf bacteria and cellular debris)
Plasma cells (help in immune response)
Mast Cells (help supply tissue with blood)
Adipocytes (store triglycerides)
White blood cells
Fuck my pretty massive ass wendy
What are the different types of connective tissue?
Loose, dense, cartilage, bone, and liquid
What is the difference between external and internal respiration?
External -o2 and co2 exchange between external environment and body cells (breathing)
Internal - cells use o2 for ATP production (cellular respiration)
What is the difference between uni and bi-directional flow?
Unidirectional air moves in one direction while in bidirectional air moves in two directions (back out the way it came)
What are the different types of respiratory pumps?
Cilia, ram ventilation (muscles), Dual pump (water flows over gills unidirectionally), buccal pump (air ventilation), and Aspiration pump (air sucked in by pressure using thorax- bidirectional flow)
What are some primary organs for respiration in vertebrates?
external and internal gills, swim bladders or lungs, skin, and mucuous
What is cutaneous respiration?
Diffusion through skin
How do gill types differentiate among fish?
Agnaths have pouched gills, cartilaginous fish have gill slits, and boney fish have an operculum over their gills,
What is the nervous system divided into?
Central nervous system (brain and spine) and peripheral nervous system (Everything else)
What is the peripheral nervous system divided into?
Somatic and autonomic nervous system
What is the autonomic nervous system divided into?
Sympathetic (fight or flight) and parasympathetic (calm) nervous systems
What are the two types of matter in the brain?
White (communication) vs grey (processing- cell bodies) matter
How are the lobes of the brain named?
What region of the skull it lies below
What is cerebrospinal fluid?
Fluid plasma baths brain and spinal cord. Gives protection and waste removal.
What are the 3 main areas of the gross anatomy of the brain?
Gyrus (wrinke), sulcus (seperates lobes), Fissure (large sulcus)
What are the three layers of the meninges (covering of the brain)?
Dura (periosteal and meningeal) (has tough fibrous connective tissue) , arachnoid (lots of blood vessels, nerves, and spinal fluid), pia (rich in blood, nerve, and spinal fluid supply)
DAP
What nerves take in stimuli and carry out responses?
Afferent (bring in) and efferent (carry out) nerves
What are three types of sensations from general sense organs?
Touch, temperature, and proprioception
How do we receive stimuli?
Special nerve cells transduces one form of energy into chemicals
What are the different types of general sensory organs?
Free sensory receptors , encapsulated sensory receptors, associated sensory receptors (wrapped around another organ)
What are 3 types of associated sensory receptors?
Proprioception, muscle spindles, golgi tendon organs
What are some special sensory organs?
Chemoreceptors, nasal passages, vomeronasal area, mouth, radiation receptors, photoreceptors, infrared receptors, mechanoreceptors, vestibular apparatus, auditory system,
What are the three components of olfaction?
Olfactory epithelium, olfactory bulb, olfactory tract
What are the three layers of the mammal eye?
Sclera, choroid, and retina
What does the retina do?
Houses the sensory cells in the eye
Are eyes different from fish to tetrapods?
Yes because different mediums affect light hitting eye
What do pupils do?
Let certain amounts of light in
Diurnal retina?
signal bipolar with single neuron
Nocturnal retina?
photoreceptors cells coverage on a small number of interneurons
Monocular vs binocular?
Monocular
Biocular (important for depth perception with both eyes)
What is an arterie?
carry blood away from the heart. have muscular elastic walls. branch to arterioles and eventually to capillaries
What is a capillary?
Have a very thin wall (quick diffusion) in order to facilitate the exchange between blood and cells.
What is a vein?
Come from the venuole that carries blood back to the heart. Elastic but less muscle in walls
What is a heart?
muscular pump to pump blood to all the cells of the body. Contains a pacemaker to regulate beating (also dependent on autonomous nervous system)
What are skeletal pumps?
Muscles within the body help push the low-pressure blood back to the heart.
What makes blood red?
Hemoglobin (and iron within it)
Do mammal red blood cells have a nucleus?
No
What is pericardium?
out sac of the heart
What are the layer of the pericardium?
Fibrous and serous (visceral and parietal)
