Introduction
The Anatomy and Physiology 1 Lab Exam 1 is designed to assess your understanding of the basic principles of human anatomy and physiology. This exam will cover the following topics:
- Skeletal system
- Muscular system
- Nervous system
- Endocrine system
- Cardiovascular system
- Respiratory system
- Digestive system
- Urinary system
- Reproductive system
Skeletal System
The skeletal system is the framework of the body. It provides support, protection, and movement. The skeletal system is made up of bones, cartilage, and joints.
Structure and Function of Bones
Bones are hard, mineralized tissues that make up the majority of the skeletal system. They provide support and protection for the body’s organs and tissues. Bones also store minerals, such as calcium and phosphorus, and produce blood cells.
Types of Bones
- Long bones: These are the long, slender bones that make up the arms and legs.
- Short bones: These are the small, cube-shaped bones that make up the wrists and ankles.
- Flat bones: These are the thin, flat bones that make up the skull and ribs.
- Irregular bones: These are the bones that do not fit into any other category, such as the vertebrae and the hip bones.
Joints
Joints are the points where two or more bones meet. There are three main types of joints:
- Synovial joints: These are the most common type of joint. They are found in the knees, elbows, and shoulders. Synovial joints are characterized by a joint cavity filled with synovial fluid, which lubricates the joint and reduces friction.
- Cartilaginous joints: These joints are found in the spine and pelvis. Cartilaginous joints are characterized by a layer of cartilage between the bones.
- Fibrous joints: These joints are found in the skull and between the teeth. Fibrous joints are characterized by a layer of fibrous tissue between the bones.
Muscular System
The muscular system is responsible for movement. The muscular system is made up of muscles, tendons, and ligaments.
Structure and Function of Muscles
Muscles are tissues that are capable of contracting. When a muscle contracts, it pulls on the tendons, which are attached to the bones. This causes the bones to move.
Types of Muscles
- Skeletal muscles: These are the muscles that are attached to the bones. Skeletal muscles are responsible for voluntary movement, such as walking, running, and jumping.
- Smooth muscles: These are the muscles that are found in the walls of organs, such as the stomach and intestines. Smooth muscles are responsible for involuntary movement, such as digestion and breathing.
- Cardiac muscle: This is the muscle that makes up the heart. Cardiac muscle is responsible for the pumping action of the heart.
Major Muscle Groups
- Upper body muscles: These muscles include the muscles of the chest, back, shoulders, and arms.
- Lower body muscles: These muscles include the muscles of the hips, thighs, and legs.
- Core muscles: These muscles include the muscles of the abdomen and back. The core muscles are responsible for stabilizing the body and protecting the spine.
Nervous System: Anatomy And Physiology 1 Lab Exam 1
The nervous system is responsible for controlling and coordinating the body’s activities. The nervous system is made up of the brain, spinal cord, and nerves.
Structure and Function of the Nervous System
The brain is the central control center of the body. The brain receives information from the senses and sends signals to the muscles and organs. The spinal cord is a long, thin bundle of nerves that runs from the brain down the back.
The spinal cord carries messages between the brain and the rest of the body.
Parts of the Brain, Anatomy and physiology 1 lab exam 1
- Cerebrum: This is the largest part of the brain. The cerebrum is responsible for higher-level functions, such as thinking, learning, and memory.
- Cerebellum: This is the part of the brain that is responsible for coordination and balance.
- Brainstem: This is the part of the brain that is responsible for basic life functions, such as breathing and heart rate.
Types of Nerves
- Sensory nerves: These nerves carry messages from the senses to the brain.
- Motor nerves: These nerves carry messages from the brain to the muscles.
- Mixed nerves: These nerves carry both sensory and motor messages.
Endocrine System
The endocrine system is responsible for regulating the body’s activities by releasing hormones. Hormones are chemical messengers that travel through the bloodstream and affect the activities of cells and organs.
Structure and Function of the Endocrine System
The endocrine system is made up of glands that produce and secrete hormones. The major endocrine glands include the pituitary gland, thyroid gland, adrenal glands, and pancreas.
Major Endocrine Glands
- Pituitary gland: This gland is located at the base of the brain. The pituitary gland is often called the “master gland” because it controls the activity of other endocrine glands.
- Thyroid gland: This gland is located in the neck. The thyroid gland produces hormones that regulate metabolism.
- Adrenal glands: These glands are located on top of the kidneys. The adrenal glands produce hormones that regulate blood pressure and stress response.
- Pancreas: This gland is located behind the stomach. The pancreas produces hormones that regulate blood sugar levels.
Hormones
Hormones are chemical messengers that are produced by the endocrine glands. Hormones travel through the bloodstream and affect the activities of cells and organs.
