Muscle Tissue Types Quiz

Muscle tissue attached to bones, enabling voluntary movement.

Involuntary muscle found only in the heart, responsible for pumping blood.

Involuntary muscle found in the walls of internal organs, controlling functions like digestion.

Individual muscle cell, the basic functional unit in muscles.

Fixed attachment point of a muscle; typically less movable.

Movable attachment point of a muscle, typically more distal.

Connective tissue connecting muscle to bone.

Skeletal muscles enable voluntary movement of limbs and body parts.

A small, round bone embedded within a tendon, often found where a tendon crosses a joint. The patella (kneecap is an example.

Hyaline cartilage covering bone ends at joints, reducing friction and absorbing shock.

The long, cylindrical shaft of a long bone; mainly compact bone, providing strength.

A layer of hyaline cartilage where bone growth occurs in children and adolescents.

A remnant of the epiphyseal plate in adults; marks where bone growth occurred.

A thin membrane lining the medullary canal and covering internal bone surfaces.

A dense layer of connective tissue covering bones, providing attachment for tendons and ligaments.

The central cavity of the diaphysis, containing yellow bone marrow.

Dense bone forming the outer layer; provides strength and support, organized into osteons.

Lighter, porous bone found at bone ends and inside; contains trabeculae, houses red bone marrow.

The fundamental unit of compact bone; concentric lamellae surrounding a central canal.

The hollow channel running through the center of an osteon, containing blood vessels and nerves.

Small cavities within bone matrix where osteocytes reside.

Tiny channels connecting lacunae, allowing communication between osteocytes.

Mature bone cells that maintain bone tissue and communicate through canaliculi.

Testosterone, the primary male sex hormone, is produced by the testes in response to luteinizing hormone (LH). It plays a crucial role in developing male secondary sexual characteristics, regulating sperm production, and influencing libido.

The epididymis is a coiled tube situated atop each testis. It consists of a single, long duct with a head, body, and tail.

The epididymis stores and matures sperm after its production in the seminiferous tubules.

The ductus deferens, also known as the vas deferens, carries sperm from the epididymis to the ejaculatory duct.

The ejaculatory duct is formed by the union of the vas deferens and the seminal vesicle duct. It carries sperm to the urethra.

The urethra is the final duct that carries semen (and urine) out of the body through the penis.

The seminal vesicles are paired glands situated behind the bladder.

Seminal vesicles produce a fructose-rich fluid that nourishes sperm and comprises a significant portion of semen.

The prostate gland surrounds the urethra just below the bladder.

The prostate gland produces a milky fluid that helps to activate sperm and contributes to semen.

The bulbourethral gland, also known as Cowper's gland, is located near the base of the penis.

The bulbourethral gland produces a clear fluid that lubricates the urethra and neutralizes acidity.

The scrotum, a pouch containing the testes, regulates their temperature.

The corpus spongiosum is the erectile tissue surrounding the urethra, preventing it from collapsing during erection.

The corpora cavernosa are two columns of erectile tissue that fill with blood during erection, causing the penis to enlarge and become rigid.

The visible, outer part of the ear, made of cartilage and skin, shaped to funnel sound waves into the ear canal.

The tube leading from the auricle to the eardrum, directing sound waves to the tympanic membrane.

A thin membrane that vibrates in response to sound waves, transmitting them to the ossicles.

Three small bones in the middle ear (malleus, incus, stapes) that amplify sound vibrations.

The first ossicle, attached to the tympanic membrane, receives sound vibrations.

The anvil-shaped ossicle that transmits vibrations between the malleus and stapes.

The stirrup-shaped ossicle that connects to the oval window of the cochlea.

A membrane-covered opening that transmits vibrations from the stapes into the cochlea.

A membrane-covered opening that allows for the displacement of fluid in the cochlea.

Connects the middle ear to the nasopharynx, equalizing pressure on both sides of the tympanic membrane.

The rigid, outer structure of the inner ear filled with perilymph fluid.

The fluid surrounding the membranous labyrinth, providing cushioning.

The flexible, inner structure of the inner ear containing endolymph fluid.

The fluid within the membranous labyrinth that helps with sound and balance.

Responsible for hearing, contains the organ of Corti.

The nerve that transmits visual information from the retina to the brain, enabling us to see.

Specialized cells in the retina responsible for capturing light and converting it into electrical signals.

Photoreceptor cells that are sensitive to low light conditions, allowing us to see in dim environments.

Photoreceptor cells responsible for color vision, enabling us to see a spectrum of colors.

A yellow spot near the center of the retina with a high concentration of cones, providing sharp central vision.

The center of the macula, containing the highest density of cones, responsible for the sharpest and most detailed vision.

A system in the inner ear that detects head movements and position relative to gravity, contributing to our sense of balance.

The 12 vertebrae in the chest region, associated with the ribs. They have facets for rib articulation, making them larger than other vertebrae.

The five largest vertebrae in the lower back, designed for weight-bearing. They are larger than the thoracic vertebrae and have a thicker body to withstand stress.

Five vertebrae fused together to form a solid structure, the sacrum. This structure connects the spine to the pelvis.

The four small, fused vertebrae at the very end of the spine. They are vestigial, meaning they represent a structure that was more significant in earlier ancestors.

The bony ring that encloses the spinal cord. It consists of two pedicles (short, thick pillars) and two laminae (flat plates).

A bony projection extending backward from the vertebral arch. These processes help support and attach muscles.

Bony projections extending laterally (sideways) from the vertebral arch, providing points for muscle and ligament attachment.

The breastbone, a flat bone located at the front of the chest. It provides attachment for ribs and protects vital organs.

The upper portion of the sternum. It connects to the clavicle (collarbone) and the first ribs.

The long, central part of the sternum. It connects to ribs 2-7, serving as an important bony junction.

The small, cartilaginous tip at the bottom of the sternum. It provides attachment for muscles.

There are three types: vertebrosternal (true ribs), vertebrochondral (false ribs), and vertebral (floating ribs).

The collarbone. It connects the arm to the body (specifically to the scapula) and helps support the shoulder joint.

The shoulder blade. It provides attachment for shoulder muscles and helps form the shoulder joint.
