| Question | Answer |
|---|---|
| Occipital | Forms the posterior part of the cranial floor and walls |
| Sphenoid | Keystone of the cranial floor |
| Covalent | A chemical bond formed by the sharing of one or more pairs of electrons between the outer shells of two atoms is called a(n) _____ bond. |
| Eight Protons | The element oxygen has an atomic number of 8, which means it contains |
| Stratum granulosum | where the process of surface keratin formation begins. |
| Stratum basale | a single layer of columnar cells. |
| Epidermis | Superficial primary layer of the skin |
| Dermis | Deep primary layer of the skin |
| Synthesis reaction | The reaction between hydrogen and oxygen needed to form water is an example of a |
| Long bones | easily identified by their roughly cylindrical shape that is longer than it is wide. |
| Diaphysis | main shaft-like portion. Its hollow, cylindrical shape and the thick compact bone that composes it adapt the diaphysis well to its function of providing strong support without adding cumbersome weight. |
| Epiphyses | the proximal and distal ends of a long bone. |
| Lysosome | This organelle is primarily a sac of powerful digestive enzymes called acid hydrolases. |
| Plasma membrane | The outer boundary of a human cell is called the |
| Peroxisome | This organelle is numerous in liver and kidney cells. |
| Golgi apparatus | This organelle has both a cis and a trans face. |
| Cytoplasm | The inside of the cell is composed largely of a gel-like substance called |
| Hyaline | Most common type of cartilage |
| Lumbar vertebrae | The vertebral bones that support the small (lower section) of the back. |
| Mandible | The bone that articulates with the temporal bone in the only movable joint of the skull |
| Muscular | System function: Powers and directs movements |
| Lymphatic | System function: Maintains constant fluid pressure by draining excess fluid from tissues, cleaning it, and recycling it to bloodstream |
| Reproductive | System function: Passes genetic code containing information for forming a body and maintaining homeostasis to offspring |
| Digestive | Maintains relatively constant nutrient level in body by digesting food and absorbing nutrients into internal environment |
| Effectors | Organs, such as muscles or glands, that directly influence controlled physiological variables |
| Positive feedback loop | Process where the output of a system amplifies or increases the initial action, leading to a self-reinforcing cycle. |
| Muscle Cell Function | Contract (shorten) to allow movement of body parts |
| Red Blood Cell Function | Transport oxygen in the bloodstream (from lungs to other parts of the body) |
| Gland Cell function | Release substances such as hormones, enzymes, mucus, and sweat |
| Immune Cells function | Recognize and destroy “nonself” cells such as cancer cells and invading bacteria |
| Nucleus | A usually central, spherical double-membrane container of chromatin (DNA) |
| Mitochondria | Tiny membranous capsule surrounding an inner, highly folded membrane embedded with enzymes |
| Microvilli | Short, fingerlike extensions of plasma membrane |
| Nucleolus | Dense area of chromatin and related molecules within nucleus |
| Angular Movement | change the size of the angle between articulating bones. |
| Carpal | between various carpal bones, movement is gliding |
| Costosternal | First rib with sternum. Movement: slight movement allows some expansion of thorax |
| Proximal Interphalangeal (PIP) Joints | The joints between the proximal and middle phalanges. |
| Distal Interphalangeal (DIP) Joints | The joints between the middle and distal phalanges. |
| Interphalangeal Joints | Hinge-type joints between the phalanges (finger bones), allowing flexion and extension. |
| Metacarpophalangeal Joint | Joints where the heads of the metacarpal bones articulate with the bases of the proximal phalanges; allow flexion, extension, and limited adduction/abduction. |
| Carpometacarpal Joints | Joints connecting the carpal (wrist) bones to the metacarpal (hand) bones; the thumb joint allows a wide range of motion including opposition. |
| Intercarpal Joints | Joints between the eight carpal bones, allowing mostly gliding movements with some abduction and flexion. |
| Scaphoid | Bone in the wrist that often fractures from falls on an outstretched hand and transmits most of the force to the radial head. |
