Appendicular skeleton consists of the bones of the upper and lower extremities, including shoulder and the hip. Skeletal system includes cartilage and ligaments that join bones together at joints. 2. Compare the properties of the intercellular collagen and elastic fibers of skeletal tissue. * Describe the intracellular matrix of bone and
LAB SIX: Joints and Body Movements This week we are studying joints and articulations. Your assignment is to answer the following questions after completing the lab. This is due by Sunday, end of week, 11:59 P.M. (MT). Submit your assignment to the Dropbox located on the silver tab at the top of the course page. Use the key terms to identify the joints described below (4 points): Key: cartilaginous fibrous synovial synovial typically allows a slight degree of movement fibrous essentially immovable joints hinge include the hip, knee, and elbow joints cartilaginous cartilage connects the bony portions Use the key terms to match the joint subcategories described below (4 points): Key: suture pivot ball and socket condyloid suture joint between most skull bones ball and socket hip joint pivot joint between the axis and atlas condyloid joint between forearm bones and wrist What characteristics do all joint have in common?
HORIZANTOL FLEXION 21. PRONATION ORIENTATION ACTIVITY 2 SKELETAL SYSTEM Label the following bones: Column Column Metatarsals Metatarsals Ribs Ribs Vertebral Vertebral Cranium Pelvis Scapula Mandible Clavicle Femur Humerus Phalanges Fibula Ulna ORIENTATION ACTIVITY 3 MAJOR JOINTS - What type of joint is it? JOINT | TYPE OF JOINT | Elbow | Hinge | Shoulder | Ball and Socket | Inter-Vertebral | | Knee | Hinge | Ankle | Gliding | QUESTIONS: 1. Define a joint? A joint is the location at which two or more bones make contact.
In compact bones, blood vessels pass through the bones periosteum, the membrane surrounding the bone, and the endosteum through perpendicular channels known as the perforating canals. These canals are conjoined with the central canal, also known as the Haversian canal, which runs the length of the bone, and houses the blood vessels and nerve cells. Surrounding the central canal are layers of bone that are often remnants of previous Haversian systems, called lamellae. Inside the layers of the lamellae are small chambers containing osteocytes, or bones cells. These chambers are known as lacunae.
Stephen McDowell Level 3 Extended Diploma in Sports & Exercise Sciences Anatomy Assignment 1 The Skeletal System The purpose of this assignment is to describe and explain the function of the skeletal system. To serve this purpose, the assignment will cover the structure of the skeleton, the bones of the skeleton, the joints of the skeleton and the range of movement available at each classification of joint. Appropriate examples are added where applicable to relate this to sport and exercise. All relevant sources have been listed in the bibliography at the end of the assignment. The human skeleton consists of approximately 206 bones all of shapes, sizes and functions.
The actual surfaces of the bones that might touch the other are the articulating surfaces, and the cartilage covering those surfaces is called articular cartilage. Periosteum: A dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints. Articular cartilage: The cartilage covering the articular surfaces of the bones forming a synovial joint. Also called arthrodial
C) a group of muscle fibers that are all part of the same motor unit. D) a group of muscle fibers and motor neurons. E) a collection of myofibrils in a muscle fiber. 3) Put the following structures in order from superficial to deep: 1. muscle fiber 2. perimysium 3. myofibril 4. fascicle 5. endomysium 6. epimysium A) 1, 5, 4, 3, 2, 6 B) 6, 2, 5, 4, 1, 3 C) 6, 2, 4, 5, 1, 3 D) 1, 3, 5, 6, 4, 2 E) 2, 3, 1, 4, 6, 5 4) Interactions between actin and myosin filaments of the sarcomere are responsible for A) muscle fatigue. B) the conduction of neural stimulation to the muscle fiber.
Excitability: The ability of muscle tissue to receive a stimulus from the nervous system. Contractility: The quality that distinguishes muscle tissue from other types of tissue. 2.) Name the three types of muscle tissue found in the human body and briefly describe the primary function of each. Skeletal muscle: attached to the bones of the skeletal system.
Which muscle type has the most elaborate connected tissue wrapping? Skeletal muscle 3. What is the striated mean relative to muscle cells? Stripped or having bands striated 4. How do the movements promoted from skeletal muscle smooth muscle?
